The Contextual Nature Of Enterprise Social Networking: A Multi Case Study Comparison

Enterprise social networking (ESN) is a relatively new phenomenon and not yet fully understood. An important reason for this lies in the fact that ESN are built on malleable technologies that do not lend themselves to immediate forms of workplace usage determined or prescribed by their features. Rather, their potential only manifests when people make sense of and incorporate them into their day-to-day work practices. In this paper we consolidate three years of case study research into ESN adoption and use. We are able to demonstrate empirically the contextual nature of ESN as an emergent phenomenon that takes on different forms in different organisational contexts. Drawing on this data we derive a theory of ESN usage, which employs a set of use cases to provide a better picture of the possibilities of ESN when appropriated into team, project or large enterprise contexts. This allows reflecting on ESN as a contextual phenomenon and social infrastructure and builds a basis for further research.
Geographic Segment Disclosure in Indonesia

The purpose of this study was to examine how Indonesian MNCs (Multinational Companies) disclosed geographic information segment. The significance of this study is highlighted by the effort to empirically investigate the initial impact of Indonesian geographic condition and Indonesian company’s behavior to respond that. Descriptive analysis was used to describe how geographic segment was used in Indonesia. The population of this study were 30 multinational companies listed in Indonesia Stock Exchange (IDX) in the period of 2015-2017. The results showed that most companies used LOB, only 18.75% of which used geographic as the main segment. They tend to disclose geographic information consistently in the number and level of specificity. The companies that used it as a secondary segment revealed a geographic basis with details, but not at a geographic level. It is the company's defense mechanism in responding to user needs and threats from competitors. Those findings help to lead a new insight regarding the implementation of segmental disclosure in the future.
Involvement of EZH2 in aerobic glycolysis of prostate cancer through miR-181b/HK2 axis

Recent studies suggest that several types of tumors preferentially metabolize glucose through aerobic glycolysis, a phenomenon known as the Warburg effect. However, it remains largely unexplored whether metabolic reprogramming is involved in prostate cancer (PCa) progression. In this study, we found that histone methyltransferase enhancer of zeste homolog 2 (EZH2) dysregulated in PCa development regulated cellular growth and aerobic glycolysis through miR-181b/hexokinase 2 (HK2) axis. Aberrant expression profiles of coding RNA and microRNA were examined by two large, independent clinical prostate cancer data sets. The results indicated that EZH2 expression was elevated followed by PCa development. A set of glycometabolism-related genes were positively correlated with EZH2 expression such as HK2. The depletion of EZH2 in cell experiments inhibited PCa cell growth and aerobic glycolysis accompanying the upregulation of miR-181b. Western blot and luciferase reporter assays showed that miR-181b inversely modulated HK2 by directly targeting the binding site within 3′-untranslated regions. Moreover, decreased miR-181b expression largely abrogated the effect of sh-EZH2 on HK2 expression and HK2-induced glucose metabolism process. Immunohistochemistry (IHC) and in situ hybridisation (ISH) analysis further revealed a significant correlation in EZH2, miR-181b and HK2 expression in nude mouse tumor xenograft. Taken together, these findings provide the first evidence that EZH2/miR-181b/HK2 pathway plays a positive role in PCa development. Targeting this aberrantly activated pathway may provide a new therapeutic strategy against PCa.
School Differences in Social–Emotional Learning Gains: Findings From the First Large-Scale Panel Survey of Students

Measures of school-level growth in student outcomes are common tools for assessing the impacts of schools. The vast majority of these measures use standardized tests as the outcome of interest, even though emerging evidence demonstrates the importance of social–emotional learning (SEL). In this article, we present results from using the first large-scale panel surveys of students on SEL to produce school-level value-added measures by grade for growth mind-set, self-efficacy, self-management, and social awareness. We found substantive differences across schools in SEL growth, with magnitudes of differences similar to those for growth in academic achievement. In contrast, we found that the goodness of fit of the value-added model was considerably lower when the outcome variables were measures of SEL constructs rather than of academic achievement. In addition, the across-school variance in the average level of the SEL measures was proportionally much smaller than that for academic measures. These findings recommend caution in interpreting measures as the causal impacts of schools on SEL, though they also do not rule out important school effects.
Respectability and reputation: Tracing intersections of race, class and gender in news discourses of violence against women

Abstract This paper investigates how gendered inequalities are reproduced in printed news media discourses of men’s violence against women and how they intersect with the racial and classed dimensions of survivor and perpetrator identities in two Cape Town newspapers. A total of 113 reports on violence against women were collected from two newspapers that drew the largest readership in the Western Cape Province between 2011 and 2013. A thematic decomposition analysis revealed the presence of a discourse of respectability, which shed light on how pathologising representations “other” and blame victims who are thought to stray from respectability, particularly poor black women who find themselves on the periphery of this discourse of femininity. In contrast, perpetrators of violence against women were represented through the lens of race and class, and predominantly through reputable performances of masculinity, silencing their accountability. Understanding violence as an intersectional experience – defined by race, class, sexuality and gender in the context of post-apartheid South Africa – is central to the analysis. A critical comparison between the two newspapers’ reporting styles is offered. Furthermore, the news media’s tendency to reproduce racial and gendered stereotypes of victims and perpetrators of violence and to marginalise some voices over others is problematised.
Prevalence and social and health correlates of insomnia symptoms among middle-and older-age persons in rural South Africa

This study investigated the prevalence and social and health correlates of insomnia symptoms among middle-and older-adults in rural South Africa. We analysed baseline survey data from the Health and Aging in Africa: A Longitudinal Study of an INDEPTH community in South Africa (HAALSI) (N = 5 059; females = 53.6%; largely African Shangaan/Tsonga-speaking). In all, 8.0% of the adults had three insomnia symptoms, 8.9% of participants had difficulty initiating sleep, 13.6% had difficulty in sleep maintenance, and 6.5% had poor sleep quality. In adjusted logistic regression, lower education, perceived unsafe neighbourhood, poorer self-rated health status, vision difficulty, pain, depressive symptoms, and posttraumatic stress disorder (PTSD) symptoms increased the odds of having insomnia symptoms. Insomnia symptoms are common in middle-and older-age adults in rural South Africa, and various risk factors were identified. This can help in improving insomnia prevention treatment in this population.
Characteristics of an Extrusion Panel Made by Applying a Modified Curing Method

CO2 emitted from building materials and the construction materials industry has reached about 67 million tons. Controls on the use of consumed fossil fuels and the reduction of emission gases are essential for the reduction of CO2 in the construction area as one reduces the second and third curing to emit CO2 in the construction materials industry. In this study, a new curing method was addressed by using a low energy curing admixture (LA) in order to exclude autoclave curing. The new curing method was applied to make panels. Then, its physical properties, depending on the mixed amount of fiber, type of fiber and mixed ratio of fiber, were observed. The type of fiber did not appear to be a main factor that affected strength, while the LA mixing ratio and mixing amount of fiber appeared to be major factors affecting the strength. Applying the proposed new curing method can reduce carbon and restrain the use of fossil fuels through a reduction of the second and third curing processes, which emit CO2 in the construction materials industry. Therefore, it will be helpful to reduce global warming.
The Effect of the REM Sleep on PeripheralVestibular Imbalance

Backgrounds and purpose: While it is known that sleep have influence on emergence of rapid eye movement (REM), namely saccades including fast component of nystagmus, whether spontaneous nystagmus due to vestibular imbalance presents during sleep is still unclear. The purpose of our study was to investigate whether tonic vestibular imbalance appeared as spontaneous nystagmus during the wakeful state could present during REM sleep. Methods: Overnight polysomnography (PSG) was performed in 7 patients with spontaneous nystagmus due to vestibular neuritis (VN) and 7 controls without dizziness or any nystagmus. The numbers of horizontal saccades were counted, during 3 minutes samples of the alert state before and after the PSG, and the first and last REM sleep. Results: All patients with VN showed significantly more saccades (fast phases of spontaneous nystagmus) towards the side contralateral to their vestibular lesion in the alert state before and after the PSG compared with control group. By contrast, during REM sleep the patients with VN showed no preponderance in saccade direction (p<0.05). Some brief nystagmoid jerks showed during REM sleep in both patients and controls equally and also had no preponderance in direction. Conclusions: The tonic vestibular imbalance at peripheral level observed during alert state does not appear at the brainstem level during REM sleep. It is suggested that a de-afferentation of the peripheral vestibular input to the REM sleep generating areas may explain an absence of nystagmus during REM sleep in patients with VN.
History of maltreatment and mental health problems in foster children: a review of the literature.

OBJECTIVE Foster children often experience compromising situations such as neglect, physical abuse, or sexual abuse before out-of-home placement. This article aims to give a literature review related to the development and mental health of foster children with special consideration of trauma history. METHODS A computer-based literature search was conducted in the databases Medline, PsycINFO, PSYNDEXplus, and SCOPUS. We determined a time frame from 1998 to 2009. RESULTS The literature search resulted in 32 articles reporting empirical data about development and mental health in foster children. Very high rates of exposure to maltreatment, developmental delays and mental disorders were found. A broad spectrum of externalizing as well as internalizing symptoms and a high prevalence of comorbid mental disorders were found. CONCLUSIONS Foster children exhibit a broad pattern of developmental problems and psychopathology. The etiology of these disorders is discussed in the context of multiple risk factors, especially that of persistent maltreatment.
The neural correlates of intertemporal decision‐making: Contributions of subjective value, stimulus type, and trait impulsivity

Making choices between payoffs available at different points in time reliably engages a decision‐making brain circuit that includes medial prefrontal cortex (mPFC), posterior cingulate cortex (PCC), and ventral striatum (VS). Previous neuroimaging studies produced differing accounts of the functions of these regions, including that these regions: (1) are sensitive to the value of rewards discounted by a function of delay ('subjective value'); (2) are differentially sensitive to the availability of an immediate reward; and (3) are implicated in impulsive decision‐making. In this event‐related fMRI study of 20 volunteers, these hypotheses were investigated simultaneously using a delay discounting task in which magnitude of rewards and stimulus type, i.e., the presence or absence of an immediate option, were independently varied, and in which participants' trait impulsivity was assessed with the Barratt Impulsiveness Scale. Results showed that mPFC, PCC, and VS are sensitive to the subjective value of rewards, whereas mPFC and PCC, but not VS, are sensitive to the presence of an immediate reward in the choice option. Moderation by individual differences in trait impulsivity was specific to the mPFC. Conjunction analysis showed significant overlap in mPFC and PCC for the main effects of subjective value and stimulus type, indicating these regions may serve multiple distinct roles during intertemporal decision‐making. These findings significantly advance our understanding of the specificity and overlap of functions subserved by different regions involved in intertemporal decision‐making, and help to reconcile conflicting accounts in the literature.

An Existential Ontology for Understanding the Experience of Psychosis

It is argued that an existential-ontological framework provides a more in-depth understanding of an individual’s experiencing of psychosis than the dominant biomedical models of psychopathology. Psychosis experience (PE) exists on a spectrum with “normal” experience instead of being defined as a discrete disease entity; and on the ontological ground of a simultaneous, reciprocal relationship between the organism and environment. First, I discuss the ontological-ontic dimensions of lived experience. I will argue that the ontological issues of Being and the nature of human existence are implicitly present in, and intertwined with, the ontic activities of psychology and psychotherapy. Second, the existential-ontological framework developed by Hersch (2015) is utilized to explain six key aspects of human experience that can be applied in, for example, the ontic task of psychotherapy that seeks to understand the lived worlds of persons with PE. While Hersch’s systematic approach owes much to Heidegger, Sartre, and Merleau-Ponty, I will also discuss these dimensions from the viewpoints of persons with PE together with other perspectives from person-centered, cognitive–behavioral and existential psychotherapies, and from neuropsychiatry.
Sibling relationships and mothers’ and fathers’ emotion socialization practices: a within-family perspective

ABSTRACT This study examined the links between mothers’ and fathers’ emotion socialization practices and social behaviour between siblings. We utilized parent reports from 57 two-parent families with preschool- and toddler-aged siblings to assess parental responses to children's negative emotions, as well as siblings’ engagement in positive involvement, conflict, and avoidance. Findings indicated that fathers’, but not mothers’, supportive and non-supportive emotion socialization strategies with the older sibling accounted for a significant amount of variance in older siblings’ rivalry, aggression, and avoidance. Additionally, older siblings’ rivalry/aggression and avoidance were positively linked to fathers’ non-supportive reactions to both the older and younger siblings’ negative emotions, highlighting the importance of a within-family approach to emotion socialization to elucidate effects across parents and siblings. Further research is needed to disentangle cause and effect relations among siblings’ socio-emotional development and parents’ emotion socialization practices.
Developing the Business Modelling Method

Currently, business modelling is an art, instead of a science, as no scientific method for business modelling exists. This, and the lack of using business models altogether, causes many projects to end after the pilot stage, unable to fulfil their apparent promise. We propose a structured method to create “as-is” business models in a repeatable manner. The method consists of the following steps: identify the involved roles, recognize relations among roles, specify the main activities, and quantify using realistic estimates of the model. The resulting business model is suitable for analysis of the current situation. This is the basis for further predictions, for example business cases, scenarios, and alternative innovations. We offer two extra steps to develop these innovations and analyse alternatives. Using them may enable successful projects to be implemented, instead of ending on a shelf after the pilot stage.
Interpreting the iISS small-gain theorem as transient plus ISS small-gain regulation

This paper addresses the problem of establishing stability of interconnections of integral input-to-state stable (iISS) systems. Recently, the small-gain theorem for input-to-state stable (ISS) systems has been extended to the class of iISS systems. It has been also proved that at least one of the two iISS subsystems comprising a feedback interconnection needs to be ISS with respect to the state of the other subsystem for guaranteeing the iISS of the overall system. This paper shows that making use of this necessary condition enables to provide more insight on the iISS small gain theorem by giving an alternative proof of this result from the perspective of transient plus ISS small-gain regulation.
A Time-Varying Parameter Model for a Forward-Looking Monetary Policy Rule Based on Real-Time Data

In this paper, we use real-time Greenbook data to analyze the time variant nature of the monetary policy conducted by the Federal Reserve. Our study improves on the existing literature by taking into account the measurement error problem associated with real-time Greenbook forecasts in a time-varying framework. Using real-time Greenbook data from 1966 to 1995 we have shown that there has been a significant change in the response of the federal funds rate to changes in expected output gap and inflation. Our results show that Federal Reserve’s response to inflation was much more aggressive in the Volcker period as compared to 1970s and 1990s. The response to output gap was significant and positive till Volcker took over and it was insignificant during his tenure. We have also found that output stabilization has become a much more important objective of the Federal Reserve after 1991.
Real-Time Scheduling Policies for Multiclass Call Centers with Impatient Customers

Motivated by call centers applications, we consider a queueing system with two classes of customers, important and low important ones. We allow customers to be impatient, that is one customer may leave the system before beginning service. We focus on scheduling policies that assign customers, upon arrival, to parallel queues, high and low priority queues. The policies are developed subject to satisfying constraints on performances related to the fraction of customers served, the mean and the variance of the waiting time in queue. We analyze several dynamic scheduling policies in order to meet our objective. These policies are characterized to be simple and easy to implement in practice
Cartesian and non-Cartesian responses in LGN, V1, and V2 cells

Cell responses to drifting Cartesian (parallel) and non-Cartesian (concentric, radial, and hyperbolic) stimuli were recorded in and beyond the classical receptive field (CRF) in the lateral geniculate nucleus (LGN), V1, and V2 of anesthetized monkeys. Many cells were equally responsive to Cartesian and non-Cartesian, especially concentric, gratings. Around 15% of cells in each area were significantly more responsive to concentric compared to parallel gratings; however, cells significantly more responsive to parallel compared to concentric gratings were more numerous in the cortex. While many cells responded to hyperbolic and radial gratings, few were most responsive to these gratings. Cell selectivity decreased for Cartesian and increased for non-Cartesian gratings from V1 to V2 and the relative response varied as a function of stimulus extent with respect to the CRF. Complex, nonoriented, nondirectional cells with a low aspect ratio (AR) responded best to non-Cartesian gratings. These results cannot be fully explained using Gabor linear/energy models of simple and complex receptive fields (RFs) although such models predict some cells to respond equally to Cartesian and non-Cartesian gratings. Cells significantly more responsive to non-Cartesian gratings can be accounted for by CRF selectivity influenced by modulation from the nonclassical receptive field (nCRF). The present study shows that Cartesian/non-Cartesian selectivity is not an emergent property of V4 cells but is present at all levels of early visual processing being subserved by a subset of cells with specific tuning properties.
Supporting Instructional Transformation Tied to Standards-Based Reforms: Examining a Learning-Focused Approach to Supporting School-Wide Implementation

ABSTRACT Across many international contexts, more recent standards-based and other educational reforms have largely intended to transform teaching. Given the importance of teacher learning to such transformations, we argue that a learning-focused support approach will be essential if such reforms are to be productively taken up by schools and teachers. We utilize existing literature on the implementation of Common Core State Standards in mathematics in the United States to extract findings of importance to a learning-focused approach for supporting school-wide implementation. Implications are generated for school leaders tasked with such work as well as for future research
Holistic Processing Predicts Face Recognition

The concept of holistic processing is a cornerstone of face-recognition research. In the study reported here, we demonstrated that holistic processing predicts face-recognition abilities on the Cambridge Face Memory Test and on a perceptual face-identification task. Our findings validate a large body of work that relies on the assumption that holistic processing is related to face recognition. These findings also reconcile the study of face recognition with the perceptual-expertise work it inspired; such work links holistic processing of objects with people’s ability to individuate them. Our results differ from those of a recent study showing no link between holistic processing and face recognition. This discrepancy can be attributed to the use in prior research of a popular but flawed measure of holistic processing. Our findings salvage the central role of holistic processing in face recognition and cast doubt on a subset of the face-perception literature that relies on a problematic measure of holistic processing.
The logistic equation and a critique of the theory of natural selection

Species coexistence is one of the central themes in modern ecology. Coexistence is a prerequisite of biological diversity. However, the question arises how biodiversity can be reconciled with the statement of competition theory, which asserts that competing species cannot coexist. To solve this problem natural selection theory is rejected because it contradicts kinetic models of interacting populations. Biological evolution is presented as a process equivalent to a chemical reaction. The main point is that interactions occur between self-replicating units. Under these assumptions biodiversity is possible if and only if species are identical with respect to the patterns of energy flow in which individuals are involved.
