Arms Race or Détente? How Interfirm Alliance Announcements Change the Stock Market Valuation of Rivals

Most prior event studies find that the announcement of a new alliance is accompanied by a positive stock market response for the partners. This result has usually been interpreted as evidence for the prevailing view that alliances are effective vehicles for partners to acquire or access new skills and thus become stronger competitors. However, partners should also earn positive abnormal returns if alliances are used to shape competitive interactions, attenuating competitive intensity industry-wide. In this study, we disentangle these different mechanisms by examining how alliance announcements affect the stock market's evaluation of allying firms' rivals: if an alliance is expected to make partner firms more competitive, this should lead to negative abnormal returns for partners' rivals; if an alliance is expected to facilitate a reduction in competitive intensity, this should lead to positive abnormal returns for rivals. Results from an event study analysis of research and development alliances in the telecommunications and electronics industries during 1996--2004 provide evidence consistent with competition attenuation in some alliances. Our research thus challenges the increasingly narrow focus on learning and resource accumulation through alliances, and calls for broader consideration of the roles and effects of collaboration, both for individual firms and for industry structure.
A General Statistical Framework for Designing Strategy-proof Assignment Mechanisms

We develop a statistical framework for the design of a strategy-proof assignment mechanism that closely approximates a target outcome rule. The framework can handle settings with and without money, and allows the designer to employ techniques from machine learning to control the space of strategy-proof mechanisms searched over, by providing a rule class with appropriate capacity. We solve a sample-based optimization problem over a space of mechanisms that correspond to agent-independent price functions (virtual prices in the case of settings without money), subject to a feasibility constraint on the sample. A transformation is applied to the obtained mechanism to ensure feasibility on all type profiles, and strategy-proofness. We derive a sample complexity bound for our approach in terms of the capacity of the chosen rule class and provide applications for our results.
Cerebral vascular effects of loading dose of dexmedetomidine: A Transcranial Color Doppler study

Background: Dexmedetomidine has been widely used in critical care settings because of its property of maintaining stable hemodynamics and inducing conscious sedation. The use of dexmedetomidine is in increasing trend particularly in patients with neurological disorders. Very few studies have focused on the cerebral hemodynamic effects of dexmedetomidine. This study is aimed to address this issue. Methods: Thirty patients without any intracranial pathology were included in this study. Middle cerebral artery flow velocity obtained from transcranial color Doppler was used to assess the cerebral hemodynamic indices. Mean flow velocity (mFV), pulsatility index (PI), cerebral vascular resistant index (CVRi), estimated cerebral perfusion pressure (eCPP), and zero flow pressure (ZFP) were calculated bilaterally at baseline and after infusion of injection Dexmedetomidine 1 mcg/Kg over 10 min. Results: Twenty-six patients completed the study protocol. After administration of loading dose of dexmedetomidine, mFV and eCPP values were significantly decreased in both hemispheres (P < 0.05); PI, CVRi, and ZFP values showed significant increase (P < 0.05) after dexmedetomidine infusion. Conclusion: Increase in PI, CVRi, and ZFP suggests that there is a possibility of an increase in distal cerebral vascular resistance (CVR) with loading dose of dexmedetomidine. Decrease in mFV and eCPP along with an increase in CVR may lead to a decrease in cerebral perfusion. This effect can be exaggerated in patients with preexisting neurological illness. Further studies are needed to evaluate the effect of dexmedetomidine on various other pathological conditions involving brain like traumatic brain injury and vascular malformations.
An analysis of safety culture attitudes in a highly regulated environment

Culture is a complex construct in organizations, consisting of attitudes, perceptions, values and beliefs, which must necessarily be set in context. Many authors imply that culture is organization-wide and common to all employees. In terms of safety culture, the organizational context may determine its salience and likelihood of affecting behaviour, especially in a highly regulated environment such as the nuclear industry. This study investigates the components of safety culture and how it varies in a highly-regulated nuclear power plant. A 60-item questionnaire measuring safety attitudes and values was administered anonymously to 1550 employees at two plants in the UK nuclear industry, with a 64.7% mean response rate. Principal components analyses revealed six factors conceptually common to shop floor and management (supervisor/manager/professional) groups for both plants, relating to: management style and communication; responsibility and commitment; risk-taking; job satisfaction; complacency; and risk awareness. A canonical discriminant analysis of the items suggested that the data could distinguish three employee groups. The implications of these findings and the proposal that there are two or more safety cultures in the organization is discussed.
The Effects of Whole-Body Vibration in Isolation or Combined with Strength Training in Female Athletes

Abstract Preatoni, E, Colombo, A, Verga, M, Galvani, C, Faina, M, Rodano, R, Preatoni, E, and Cardinale, M. The effects of whole-body vibration in isolation or combined with strength training in female athletes. J Strength Cond Res 26(9): 2495–2506, 2012—The aims of this study were to assess the behavior of a vibrating platform under different conditions and to compare the effects of an 8-week periodized training program with whole-body vibration (WBV) alone or in combination with conventional strength training (ST). Vibrating frequencies, displacements, and peak accelerations were tested through a piezoelectric accelerometer under different conditions of load and subjects' position. Eighteen national-level female athletes were assigned to 1 of 3 different groups performing WBV, conventional ST, or a combination of the 2 (WBV + ST). Isometric maximal voluntary contraction, dynamic maximal concentric force, and vertical jump tests were performed before and after the conditioning program. Vibrating displacements and maximum accelerations measured on the device were not always consistent with their expected values calculated from the display and manufacturers' information (sinusoidal waveforms). The WBV alone or in combination with low-intensity resistance exercise did not seem to induce significant enhancements in force and power when compared with ST. It appears that WBV cannot substitute parts of ST loading in a cohort of young female athletes. However, vibration effects might be limited by the behavior of the commercial platforms as the one used in the study. More studies are needed to analyze the performances of devices and the effectiveness of protocols.
Responding to Hate Crimes through Restorative Justice Dialogue

Hate promotes violence. Dialogue among conflicting parties and groups is one way to decrease hate and help prevent bias‐motivated crimes. Restorative justice has emerged in the last three decades as a means of giving all who are stake‐holders in a crime—victims, offenders, and the community to which they belong—a voice in how harm can be repaired and future harm prevented. The present article reports on a two‐year study of seven communities that utilized elements of a restorative justice dialogue approach as one component of responding to bias‐motivated crimes and hate‐charged situations. Following presentation of three case studies, the article highlights the invitational nature of such dialogue, the preparation of participants, and the dialogue process. It also examines factors that influence the dialogue, including the intense impact of hate crimes, the role of the media, and the involvement of outside interest groups. Finally, it explores ways to sustain the dialogue after the crisis recedes.
Investigating directionality for a media consumption construct: Establishing the utility of confirmatory vanishing tetrad analysis

Purpose – When assessing the psychometric properties of measures and estimate relations among latent variables, many studies in the social sciences (including management and marketing) often fail to comprehensively appraise the directionality of indicants. Such failures can lead to model misspecification and inaccurate parameter estimates. The purpose of this paper is to apply a post hoc test called confirmatory vanishing tetrad analysis (CTA hereafter) to a single construct called mass media consumption information exposure, which antecedent studies conceptually posited to be a formative (causative) representation.Design/methodology/approach – This paper analyses a consumer sample of 585 US respondents and applies the CTA test to a single construct by its inclusion in various matrices within a statistical analysis system‐macro that takes into account nonnormal data characteristics. The matrices are derived from Mplus 5 through the estimation of a single‐factor congeneric model. The CTA test calculates a .
Major constituents and two dependency grammar constraints on sharing in coordination

Abstract The article examines the usage of the “major constituent” concept in theories of coordination. The literature on coordination references major constituents when predicting the material that may and may not be shared by the conjuncts of coordinate structures. Previous attempts at defining the concept are, however, vague and insufficient. Hence the article presents a new definition. This definition is based in a dependency grammar framework. In addition to this new definition, two constraints are proposed that help predict which material can be shared in coordination. The first constraint, called the Restriction on External Sharing (RES) predicts which material external to coordinate structures can be shared. The second constraint, called the Restriction on Internal Sharing (RIS), predicts which material internal to the initial conjunct can be shared. A central aspect of the approach is the distinction between conjunct-external and conjunct-internal sharing. Various data are examined that demonstrate the validity of this distinction.
Inspired by El Duende: One-Canvas Process Painting in Art Therapy Supervision

Abstract This article describes an art-based approach to supervision that combines clinical insights with archetypal awareness arising from painting on a single canvas throughout the internship semester. Supervision is comprised of three main components: (a) spontaneous painting, (b) complex reflective processing, and (c) aesthetically focused attention to imagery appearing in the painting that parallels the internship experience. Inspired by the artistic struggle of el duende to bring forth emotional vibrancy, a central aspect of the model is the supervisee's relationship to a single canvas that transforms awareness through sequential layering, that welcomes tension, and that potentially integrates personal and professional identities.
Resource-Based Determinants of Online Channel Commitment and Performance

While some firms' entire business models revolve around online channels, others have made only limited commitments to online channel ventures. What accounts for this marked heterogeneity, and do firms reap the performance benefits of increased levels of commitment? Drawing on findings from the literature on innovation and insights from the resource-based view (RBV) of the firm, we propose an integrative conceptual framework that helps answer these questions. We ground our hypotheses in the context of retailers' online channel development efforts, and test our conceptual framework with data collected via a web-based survey of 550 retailers. We find evidence of significant positive returns to investments in online channels. Furthermore, we observe the divergent effects of different sets of capabilities on commitment and performance. Importantly, we find that even after controlling for commitment, firms' resources have a significant impact on the performance of the online channel.
Be happy and believe in your capacity: Establishing link between subjective well-being and self-efficacy among Filipino adolescents

The study describes the relationship between the degree of subjective well-being and level of self-efficacy among the intended populace. Two hundred adolescents (131 female and 69 male) who were part of the larger population of individuals whose age ranges from 15 to 19 in a private sectarian college were selected and asked to answer Oxford Happiness Questionnaire (OHQ) and General Self Efficacy Scale (GSE). The study employed a descriptive-correlational research design. After collecting the questionnaires among the subjects and analyzing the data using SPSS 17.0 software, it was revealed that subjective well-being is significantly related to self-efficacy (r=.32, p<.01). The researcher also looked into the possible implications of this finding to the population at hand.
Impact of a Confounding Variable on a Regression Coefficient

Regression coefficients cannot be interpreted as causal if the relationship can be attributed to an alternate mechanism. One may control for the alternate cause through an experiment (e.g., with random assignment to treatment and control) or by measuring a corresponding confounding variable and including it in the model. Unfortunately, there are some circumstances under which it is not possible to measure or control for the potentially confounding variable. Under these circumstances, it is helpful to assess the robustness of a statistical inference to the inclusion of a potentially confounding variable. In this article, an index is derived for quantifying the impact of a confounding variable on the inference of a regression coefficient. The index is developed for the bivariate case and then generalized to the multivariate case, and the distribution of the index is discussed. The index also is compared with existing indexes and procedures. An example is presented for the relationship between socioeconomic background and educational attainment, and a reference distribution for the index is obtained. The potential for the index to inform causal inferences is discussed, as are extensions.
Solitary Tracheobronchial Papilloma: Cytomorphology and ancillary studies with histologic correlation

Solitary tracheobronchial papilloma (STBP) is a rare benign tumor that primarily involves the tracheobronchial tree. Human papilloma virus (HPV) infection is associated with dysplasia and a high risk of carcinoma in these lesions. The cytomorphology of STBP is not well established in the literature. Our aim is to characterize the cytomorphologic features of STBP, with histologic correlation in a series of 6 patients — 4 males and 2 females — with a mean age of 67 years (range, 53-88 years). There were 5 biopsy-proven squamous papillomas and 1 glandular papilloma. On surgical biopsy, squamous papillomas exhibited cytological atypia (4 graded mild and 1 graded moderate with focal severe dysplasia), surface erosion, and inflammation. Cytology specimens available for review included a combination of 4 fine-needle aspirations (FNAs), 2 bronchoalveolar lavages and 2 (of 3) bronchial brushings. Cytologic findings associated with squamous papillomas included atypical squamous cells and rare squamous cell resembling koilocyte in 1 bronchial brushing. Sheets of squamous cells were identified in another specimen. Several cases had a prominent background of acute inflammation, and candida was present in 1 specimen. HPV in-situ hybridization was positive in 1 case and negative in 2 cases. A p16 immunocytochemical stain performed on 1 cell block was negative. In conclusion, although STBP is a rare neoplasm, these cases may be encountered in respiratory cytology samples. FNA of papillomas yields fewer lesional cells compared to exfoliative samples. These lesions may be mistaken in cytology specimens for squamous cell carcinoma, squamous-lined cavitary lesions, an infectious (fungal) process, reactive squamous metaplasia, or oral contamination.
Integrated NY-ESO-1 antibody and CD8+ T-cell responses correlate with clinical benefit in advanced melanoma patients treated with ipilimumab

Ipilimumab, a monoclonal antibody against cytotoxic T lymphocyte antigen 4 (CTLA-4), has been shown to improve survival in patients with advanced metastatic melanoma. It also enhances immunity to NY-ESO-1, a cancer/testis antigen expressed in a subset of patients with melanoma. To characterize the association between immune response and clinical outcome, we first analyzed NY-ESO-1 serum antibody by ELISA in 144 ipilimumab-treated patients with melanoma and found 22 of 140 (16%) seropositive at baseline and 31 of 144 (22%) seropositive following treatment. These NY-ESO-1–seropositive patients had a greater likelihood of experiencing clinical benefit 24 wk after ipilimumab treatment than NY-ESO-1–seronegative patients (P = 0.02, relative risk = 1.8, two-tailed Fisher test). To understand why some patients with NY-ESO-1 antibody failed to experience clinical benefit, we analyzed NY-ESO-1–specific CD4+ and CD8+ T-cell responses by intracellular multicytokine staining in 20 NY-ESO-1–seropositive patients and found a surprising dissociation between NY-ESO-1 antibody and CD8 responses in some patients. NY-ESO-1–seropositive patients with associated CD8+ T cells experienced more frequent clinical benefit (10 of 13; 77%) than those with undetectable CD8+ T-cell response (one of seven; 14%; P = 0.02; relative risk = 5.4, two-tailed Fisher test), as well as a significant survival advantage (P = 0.01; hazard ratio = 0.2, time-dependent Cox model). Together, our data suggest that integrated NY-ESO-1 immune responses may have predictive value for ipilimumab treatment and argue for prospective studies in patients with established NY-ESO-1 immunity. The current findings provide a strong rationale for the clinical use of modulators of immunosuppression with concurrent approaches to favor tumor antigen-specific immune responses, such as vaccines or adoptive transfer, in patients with cancer.
Evidence in the Spanish language press of linguistic borrowings of computer and Internet-related terms

With the rise of the Internet, English has become a source of borrowing of computer terms in many languages, including Spanish. Many of these borrowings are rapidly making their way into the Spanish language press. A survey of newspapers from eight Latin American countries yielded a total of 231 lexical borrowings of different types, all related to broad fields, such as software, hardware, data, and Internet-related terms. These borrowings can be classified as loanwords, calques of various kinds, including loan translations and semantic extensions, and loanblends. Many have already appeared in monolingual Spanish dictionaries, such as the Diccionario de la Real Academia, and in a number of dictionaries of Hispanic Anglicisms.
Electroencephalographic Analysis in Communication Science: Testing Two Competing Models of Message Production

Electroencephalographic (EEG) analysis allows measurement of electrical activity in bundles of neurons around electrodes placed at various locations on the scalp. In this essay, we provide an overview of the biological basis of EEG methodology and outline basic principles and practices of data collection. We conducted a study using EEG to test expectations from two competing cognitive theories of communication—computational theory and dynamic memory theory. Participants (N = 30) were assigned to one of two conditions—routine talk and direction-giving. EEG was used to measure the electrical activity in the dorsolateral prefrontal cortex (DLPFC), an area of the brain that is associated with message production. Results indicated that DLPFC activity was far more suggestive of dynamic memory theory. Specifically, electrical activity in the DLPFC was significantly lower during routine talk than during direction-giving. We discuss the implications of our findings and the limitations of EEG methods in communication research.
Evaluation of Various Methods of Assessing Symptoms of Cognitive Impairment and Dementia

Background and PurposeThe effect of different diagnostic criteria for detecting dementia in both epidemiological and stroke cohort studies has been shown, but comparison between different assessment methods has only seldom been done. We compared both assessment methods and diagnostic criteria for dementia in a large well-defined stroke cohort. Subject and MethodsA group of 227 of 486 patients aged 55 to 85 years who 3 months after ischemic stroke completed a comprehensive neuropsychological test battery, structured clinical mental status examination of defined cognitive domains with expanded Mini-Mental State Examination. The criteria for dementia were those of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III, DSM-III-R) and the National Institute of Neurological Disorders and Stroke-Associated Internationale pour la Reserche et l'Enseignement en Neurosciences (NINDS-AIREN). ResultsThe main differences between clinical and neuropsychological examinations were seen in memory functions: clinically 24.7% and neuropsychologically 54.2% had impairment in short-term memory and 10.4% versus 5.3% in long-term memory. Accordingly, the prevalence of dementia varied greatly: It was clinically 14.1% by DSM-III, 9.7% by DSM-III-R and 8.4% by NINDS-AIREN criteria. The corresponding frequencies based on neuropsychological evaluation were 27.3%, 4.0% and 25.6%. Between these 3 diagnostic criteria the concordance varied in clinical testing between 59.4%-68.8% (kappa 0.72–0.79) and in neuropsychological testing between 14.5%–81.1% (kappa 0.20–0.86). The concordance between clinical and neuropsychological testing was 56.8% (kappa 0.42) by DSM-III , 31.6% (kappa 0.35) by DSM-III-R and 25.5% (kappa 0.24) by NINDS-AIREN. ConclusionsThe frequency of poststroke dementia and cognitive decline varied sharply when different systems of diagnostic classification and methods were used. This may have serious influences on investigation and treatment of patients. We underline the importance of further debate and studies to refine the categories of cognitive impairment used in the setting of CVD.
Relationship of Motivation, Strategic Learning, and Reading Achievement in Grades 5, 7, and 9

Abstract The relationships among attributional beliefs, self-perception of competence, knowledge, and reported use of learning and reading strategies and reading achievement were investigated. Subjects included 104 Grade 5, 133 Grade 7, and 101 Grade 9 students with and without learning difficulties. Results provided empirical support for a close relationship between motivation and strategic learning proposed in recent metacognitive theories. Although the motivation variables had a more important role than strategic learning in explaining achievement variance in the younger grades, strategic learning was found to mediate between the effects of motivation on reading achievement in Grade 9. Further, a pattern of learned helplessness was observed among the poor learners in the study. Implications of these findings for instruction are discussed.
