Losses From Horizontal Merger: The Effects of an Exogenous Change in Industry Structure on Cournot-Nash Equilibrium

The consequences of a horizontal merger are typically studied by treating the merger as an exogenous change in market structure that displaces the initial Cournot equilibrium. In the new equilibrium the merged firm is assumed to behave like a multiplant Cournot player engaged in a noncooperative game against other sellers. The purpose of this article is to evaluate an unnoticed comparative-static implication of this approach: some exogenous mergers may reduce the endogenous joint profits of the firms that are assumed to collude. Cournot's original example is used to illustrate this and other bizarre results that can occur in the Cournot framework if the market structure is treated as exogenous.
The (Normal) Rate of Capacity Utilization at the Firm Level

This paper examines the endogeneity (or lack thereof) of the rate of capacity utilization in the long run at the firm level. We provide economic justification for the adjustment of the desired rate of utilization toward the actual rate on behalf of a cost-minimizing firm after examining the factors that determine the utilization of resources. The cost-minimizing firm has an incentive to increase the utilization of its capital if the rate of the returns to scale decreases as its production increases. The theory of economies of scale provides justification for this kind of behavior. In this manner, the desired rate of utilization becomes endogenous.
The lateral ventromedial thalamic nucleus spreads nociceptive signals from the whole body surface to layer I of the frontal cortex

Neurons within the lateral ventromedial thalamic nucleus (VMl) convey selectively nociceptive information from all parts of the body. The present experiments were performed in rats and were designed to determine the organization of cortical projections from VMl neurons. In a first series of experiments, these cells were characterized electrophysiologically and individually labelled in a Golgi‐like manner following juxtacellular electrophoresis of biotin–dextran. In a second experimental series, topical applications of the tracers fluorogold and tetramethylrhodamine‐labelled dextran were placed into both the rostral‐most and caudal areas of layer I of the dorsolateral frontal cortex, respectively. All VMl nociceptive neurons were fusiform and their full dendritic arborizations were bipolar, extending in the lateromedial axis. VMl cells are thus particularly well located to receive widespread nociceptive inputs via a brainstem link, viz. the medullary subnucleus reticularis dorsalis. VMl neurons driven by ‘whole body’ nociceptive receptive fields project to the rostral part of the layer I of the dorsolateral frontal cortex. These projections are widespread because double‐labelling data showed a great number of VMl neurons labelled from both rostral and caudal dorsolateral cortices. The VMl comprises a homogeneous, organized subset of thalamic neurons that allow any signals of pain to modify cortical activity in a widespread manner, by interacting with the entire layer I of the dorsolateral neocortex.
Feasibility of Optical Coherence Tomography (OCT) for Intra-Operative Detection of Blood Flow during Gastric Tube Reconstruction

In this study; an OCT-based intra-operative imaging method for blood flow detection during esophagectomy with gastric tube reconstruction is investigated. Change in perfusion of the gastric tube tissue can lead to ischemia; with a high morbidity and mortality as a result. Anastomotic leakage (incidence 5–20%) is one of the most severe complications after esophagectomy with gastric tube reconstruction. Optical imaging techniques provide for minimal-invasive and real-time visualization tools that can be used in intraoperative settings. By implementing an optical technique for blood flow detection during surgery; perfusion can be imaged and quantified and; if needed; perfusion can be improved by either a surgical intervention or the administration of medication. The feasibility of imaging gastric microcirculation in vivo using optical coherence tomography (OCT) during surgery of patients with esophageal cancer by visualizing blood flow based on the speckle contrast from M-mode OCT images is studied. The percentage of pixels exhibiting a speckle contrast value indicative of flow was quantified to serve as an objective parameter to assess blood flow at 4 locations on the reconstructed gastric tube. Here; it was shown that OCT can be used for direct blood flow imaging during surgery and may therefore aid in improving surgical outcomes for patients.
Transferring irrigation management to farmer's associations: evidence from the Philippines.

Irrigation management transfer (IMT) is an important strategy among donors and governments that aims to strengthen farmer control over water and irrigation infrastructure. In this study, we use data from a survey of 68 irrigator associations (IAs) and 1020 farm households in the Philippines to examine the impact of IMT on irrigation association performance and on rice yields. We find that the presence of IMT is associated with an increase in maintenance activities undertaken by irrigation associations. While associations with and without IMT contracts undertake canal maintenance, the frequency of maintenance in IMT IAs is higher. IMT presence is also associated with an increase in farm yields by about 6%; rice production in IMT areas is higher even after we control for various differences amongst rice farmers in IMT and non-IMT areas. Finally, IMT may even give poorer farmers a small boost in terms of rice yields. We speculate that this boost may be a result of improved water delivery and better resolution of conflicts related to illegal use.
OLIGOCELLULA1/HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES15 Promotes Cell Proliferation With HISTONE DEACETYLASE9 and POWERDRESS During Leaf Development in Arabidopsis thaliana

Organ size regulation is dependent on the precise spatial and temporal regulation of cell proliferation and cell expansion. A number of transcription factors have been identified that play a key role in the determination of aerial lateral organ size, but their functional relationship to various chromatin modifiers has not been well understood. To understand how leaf size is regulated, we previously isolated the oligocellula1 (oli1) mutant of Arabidopsis thaliana that develops smaller first leaves than the wild type (WT) mainly due to a reduction in the cell number. In this study, we further characterized oli1 leaf phenotypes and identified the OLI1 gene as well as interaction partners of OLI1. Detailed characterizations of leaf development suggested that the cell proliferation rate in oli1 leaf primordia is lower than that in the WT. In addition, oli1 was associated with a slight delay of the progression from the juvenile to adult phases of leaf traits. A classical map-based approach demonstrated that OLI1 is identical to HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES15 (HOS15). HOS15/OLI1 encodes a homolog of human transducin β-like protein1 (TBL1). TBL1 forms a transcriptional repression complex with the histone deacetylase (HDAC) HDAC3 and either nuclear receptor co-repressor (N-CoR) or silencing mediator for retinoic acid and thyroid receptor (SMRT). We found that mutations in HISTONE DEACETYLASE9 (HDA9) and a switching-defective protein 3, adaptor 2, N-CoR, and transcription factor IIIB-domain protein gene, POWERDRESS (PWR), showed a small-leaf phenotype similar to oli1. In addition, hda9 and pwr did not further enhance the oli1 small-leaf phenotype, suggesting that these three genes act in the same pathway. Yeast two-hybrid assays suggested physical interactions, wherein PWR probably bridges HOS15/OLI1 and HDA9. Earlier studies suggested the roles of HOS15, HDA9, and PWR in transcriptional repression. Consistently, transcriptome analyses showed several genes commonly upregulated in the three mutants. From these findings, we propose a possibility that HOS15/OLI1, PWR, and HDA9 form an evolutionary conserved transcription repression complex that plays a positive role in the regulation of final leaf size.
Clinical Reasoning: A 51-year-old man with cervical pain and progressively deteriorating gait

A 51-year-old Caucasian man presented with cervical pain, right hand weakness, and progressively deteriorating gait. Onset of symptoms occurred 1 month before admission with cervical pain that worsened during neck flexion. A few days later he noticed reduced dexterity and numbness of his right hand. During the following 3 weeks, his gait became increasingly unstable. Additionally, he reported erectile dysfunction and urinary hesitancy. No previous trauma was recalled. His medical and family history was unremarkable except for hypertension that was treated with angiotensin-converting enzyme inhibitors.
A New Measure of Life Satisfaction: The Riverside Life Satisfaction Scale

ABSTRACT The Satisfaction With Life Scale (Diener, Emmons, Larsen, & Griffin, 1985) has been the dominant measure of life satisfaction since its creation more than 30 years ago. We sought to develop an improved measure that includes indirect indicators of life satisfaction (e.g., wishing to change one's life) to increase the bandwidth of the measure and account for acquiescence bias. In 3 studies, we developed a 6-item measure of life satisfaction, the Riverside Life Satisfaction Scale, and obtained reliability and validity evidence. Importantly, the Riverside Life Satisfaction Scale retained the high internal consistency, test–retest stability, and unidimensionality of the Satisfaction With Life Scale. In addition, the Riverside Life Satisfaction Scale correlated with other well-being measures, Big Five personality traits, values, and demographic information in expected ways. Although the Riverside Life Satisfaction Scale correlated highly with the Satisfaction With Life Scale, we believe it improves the Satisfaction With Life Scale by appropriately increasing construct breadth and reducing the potential for bias.
The international competitiveness of Asian firms

Purpose – Conventional studies of international competitiveness use country‐level data, but the aim of this paper is to extend this work by using firm level data of large Asian firms.Design/methodology/approach – The authors gathered the regional sales and assets data for large Asian firms listed in latest Fortune Global 500 from their annual reports. They then applied the data to the firm specific advantage/country specific advantage matrix and the regional matrix frameworks developed by Rugman.Findings – It is found that most Asian firms do not operate globally, but focus on their home region. Thus, Asian firms exploit and develop their FSAs regionally. Only a few large Japanese and Korean firms have significant sales outside of Asia. Large Asian firms vie with their regional competitors in their home region market.Originality/value – International competitiveness does not necessarily mean globalization or global competition. International strategic management should consider the reality of regional com.
The Importance of Change: Changes at a Teacher Education College in Israel--Declared and Perceived Aspects.

This study examines changes at a large teacher education college in Israel and considers how teacher educators perceive these changes. The research tools included protocols documenting formal meetings of college decision makers, questionnaires distributed among the college teaching faculty, analyzed quantitatively, and in-depth narrative interviews with twenty faculty members, analyzed for qualitative content. Results point to two aspects of change: the declared aspect of the college decision makers and the perceived aspect of the teacher educators who must implement decision makers' policy. Findings indicate that the two aspects do not entirely coincide, though they overlap on some parameters, especially those related to the teaching environment and to the well-being of teacher educators.
On the Value of Restrictive Covenants: Empirical Investigation of Public Bond Issues

Are restrictive covenants effective mechanisms in mitigating agency problems? Is the magnitude of the increase in the cost of debt due to agency problems non-trivial? We tackle these questions using a large dataset of public bonds. Contrary to the view that restrictive covenants in public bond contracts are standard boilerplates that serve little purpose, we find significant benefits in terms of reduction in the cost of debt associated with covenants. Restrictions on investment activities or issuance of higher priority claims reduce the cost of debt by about 35–75 basis points. These findings suggest that investors view bond covenants as important instruments in mitigating agency problems, and an increase in the cost of debt due to agency problems could be substantial. Additionally, we find that high growth firms and firms with low probability of default are less likely to include covenants suggesting that the costs of covenants outweigh benefits for these types of firms.
The antecedents of training activity in British small and medium-sized enterprises

Analysing data from the 1998 Workplace Employee Relations Survey we establish the extent to which levels of training activity in Britain are lower in SMEs than in larger firms.The antecedents of training activity within the SME sector are examined in terms of the workplace characteristics that are associated with high or low levels of training. Both managers and non-managers receive less training in SMEs compared with larger organizations.Training in the SME sector is associated with larger SMEs, multi-site SMEs, franchises, the presence of a personnel/HR specialist and multiple memberships of business advisory networks. Neither Investors in People nor trade union recognition are associated with greater training activity.The implications of the findings for government policy regarding training in SMEs are discussed.
More than lip service: linking the intensity of empowerment initiatives to individual well-being and performance

We conceptualize empowerment initiatives as varying in terms of intensity – or the degree to which the intervention is rhetorical (aiming to influence employees' sense of control at work, what we refer to as surface empowerment) as opposed to actual (aiming to influence the actual degree of employee job authority, what we refer to as deep empowerment). We then test the effects of rhetorical vs. actual empowerment interventions on employee well-being and performance, as well as the degree to which self-efficacy mediates these effects on the basis of a simulation-based experiment. Results indicate that although both surface and deep empowerment initiatives have beneficial effects on individual well-being, only the latter results in performance increase. We also find that self-efficacy fully mediates the association between surface empowerment (as compared with non-empowerment) and well-being, but only partially mediates the association between deep empowerment (as compared with non-empowerment) and well-being.
KIBRA Genetic Polymorphism Influences Episodic Memory in Alzheimer’s Disease, but Does Not Show Association with Disease in a Japanese Cohort

Background/Aims: A single-nucleotide polymorphism (SNP) in the KIBRA gene, rs17070145, was reported to be significantly associated with episodic memory in cognitively normal cohorts. This observation has expanded genetic studies on KIBRA to Alzheimer’s disease (AD). Importantly, the association between KIBRA and episodic memory in AD has never been addressed. In this study, we investigated whether the KIBRA rs17070145 SNP influences AD episodic memory and the disease in a Japanese cohort. Methods: Blood samples from 346 AD patients and 375 normal cognitive controls were collected and genotyped for rs17070145. Episodic memory was measured in 32 AD patients, diagnosed for the first time, by use of the Rivermead Behavioral Memory Test (RBMT). Results: We found that KIBRA C allele carriers scored significantly lower than KIBRA non-C carriers on both RBMT total profile score (p = 0.042, effect size = 0.84) and RBMT total screening score (p < 0.001, effect size = 1.42). The KIBRA gene did not show association with AD in our Japanese cohort. Conclusion: Our results evidence a strong association between the KIBRA gene and episodic memory impairment in AD, but show no influence on AD in our Japanese cohort. We propose that KIBRA might have an effect similar to cognitive reserve.
Low wages and policy options in the Republic of Korea: Are policies working?

: Despite the introduction and expansion of collective bargaining, minimum wages and unemployment and in-work benefits, low pay is increasingly common in the Republic of Korea. This is at odds with much of the literature – including the ILO's Global Wage Report 2010/11 – which suggests that protective policies will curb low pay. Focusing on the Republic of Korea, the authors examine this intriguing paradox and conclude that while the appropriate policy “menu” was implemented, its effectiveness was limited by incomplete coverage and insufficient benefit levels. They suggest this disappointing situation represents not only a labour market failure, but also a policy failure.
The Advantages Perceived by School Teachers in Engaging Their Students in University-Based Chemistry Outreach Activities.

The value teachers put on university-based outreach activities designed for 14 -16 year olds that involves both practical and lecture activities are discussed. A variety of good reasons for attending are provided by the teachers but the role of a School Teacher Fellow in mapping the events to the curriculum is shown to be vital to the success of any event. The pre-event difficulties needing to be overcome in engaging with universities are discussed with health and safety and in particular paperwork associated with this being cited as a particular barrier to engagement.
Numerical Modelling of Double-Steel Plate Composite Shear Walls

Double-steel plate concrete composite shear walls are being used for nuclear plants and high-rise buildings. They consist of thick concrete walls, exterior steel faceplates serving as reinforcement and shear connectors, which guarantee the composite action between the two different materials. Several researchers have used the Finite Element Method to investigate the behaviour of double-steel plate concrete walls. The majority of them model every element explicitly leading to a rather time-consuming solution, which cannot be easily used for design purposes. In the present paper, the main objective is the introduction of a three-dimensional finite element model, which can efficiently predict the overall performance of a double-steel plate concrete wall in terms of accuracy and time saving. At first, empirical formulations and design relations established in current design codes for shear connectors are evaluated. Then, a simplified finite element model is used to investigate the nonlinear response of composite walls. The developed model is validated using results from tests reported in the literature in terms of axial compression and monotonic, cyclic in-plane shear loading. Several finite element modelling issues related to potential convergence problems, loading strategies and computer efficiency are also discussed. The accuracy and simplicity of the proposed model make it suitable for further numerical studies on the shear connection behaviour at the steel-concrete interface.
Reduction of the effective corporate tax burden in Romania 1992–2012 and Romania's current ranking among the Central and Eastern European EU member states

This article traces Romania's development to a low-tax country among the member states of the European Union by analysing the major tax law changes in corporate taxation since 1992. We compute and compare the effective company tax burdens of a European model company at different points of time which constitute milestones in the development of corporate taxation in Romania. We find that the significant reduction of the corporate income tax rate from 45% in 1992 to 16% since 2005 has not been accompanied by a comprehensive broadening of the corporate income tax base as it has been in many longstanding member states of the EU and the OECD. Since 1992 the average company tax burden of the underlying model company has dropped by almost 65%. As a result, Romania holds second position among the group of Central and Eastern European EU member states.
BlazeIt: Fast Exploratory Video Queries using Neural Networks

As video volumes grow, analysts have increasingly turned to deep learning to process visual data. While these deep networks deliver impressive levels of accuracy, they execute as much as 10x slower than real time (3 fps) on a $8,000 GPU, which is infeasible at scale. In addition, deploying these methods requires writing complex, imperative code with many low-level libraries (e.g., OpenCV, MXNet), an often ad-hoc and time-consuming process that ignores opportunities for cross-operator optimization. To address the computational and usability challenges of video analytics at scale, we introduce BLAZEIT, a system that optimizes queries over video for spatiotemporal information of objects. BLAZEIT accepts queries via FRAMEQL, a declarative language for exploratory video analytics, that enables video-specific query optimization. We propose new query optimization techniques uniquely suited to video analytics that are not supported by prior work. First, we adapt control variates to video analytics and provide advances in specialization for aggregation queries. Second, we adapt importance-sampling using specialized NNs for cardinality-limited video search (i.e. scrubbing queries). Third, we show how to infer new classes of filters for content-based selection. By combining these optimizations, BLAZEIT can deliver over three order of magnitude speedups over the recent literature on video processing.
Undistorted linear Bi chains with hypervalent bonding in La3TiBi5 from single-crystal X-ray diffraction.

The crystal structure of the lanthanum titanium bismuthide La3TiBi5 (Pearson code hP18, Wyckoff sequence b d g2) has been established from single-crystal X-ray diffraction data and analyzed in detail using first-principles calculations. There are no anomalies pertaining to the atomic displacement parameter of the Ti site, previously reported based on a powder X-ray diffraction analysis of this compound. The anionic substructure contains columns of face-sharing TiBi6 octahedra and linear Bi chains. Due to a significant La(5d) and Bi(6p) orbital mixing, a perfectly one-dimensional character of the Bi chains is not realised, while a three-dimensional electronic structure is established instead. The latter fact explains the stability of the polyanionic pnictide units against Peierls distortions. The hypervalent bonding in the Bi chains is reflected in a rather long Bi-Bi distance of 3.2264 (4) Å and a typical pattern of bonding and antibonding interactions, as revealed by electronic structure calculations.
What Managerial Leadership Behaviors do Student Managerial Leaders Need? An Empirical Study of Student Organizational Members

Student leadership is a buzzword on most university campuses. However, recent research indicates that the leadership learning assumed to be taking place may not have happened at the depth currently believed. One explanation is that, as management education and development scholars, we are not clear on what leadership skills these student leaders require. This manuscript identifies the critical managerial leadership behaviors these student leaders need to successfully move their student organizations forward. It is based on empirical data from student members of the very organizations the student leader is trying to influence.
