Organizational culture measurement: A component approach

As a part of wide research of reintegration of human resources of economy in transition, a new method of identification and measurement of components of organizational culture was shown in this study. Beside usual organizational parameters, in identification of cultural patterns of organizational behavior included were: a perception of employee roles, the role of a director, the locus of control, and subjects' interests. Such an approach is taking into consideration the fact that different components are not at the same general level and depth in organizational culture, and consequently not equally prone to changes. In this research, the sample consisted of 880 employees in six different working organizations from different towns of Yugoslavia. The research was done during 2002. Five special instruments have been developed to meet the outlined conceptualization of the components of organizational culture. Hierarchical factor analysis derived 13 relatively independent components of organizational culture.
Up for Grabs? Sexual Objectification as a Mediator Between Women’s Alcohol Use and Sexual Victimization

Sexual objectification, the tendency to reduce women to their bodies, body parts, or sexual functions for use by others, has been theorized to set the stage for more severe acts of violence but has been largely absent from the existing sexual victimization literature. The purpose of this study was to explore the role of sexual objectification in mediating the well-established link between women’s alcohol use and sexual victimization. A large sample of undergraduate women (N = 673) reported their alcohol use (frequency and quantity), experiences of sexual objectification (body evaluation and unwanted explicit sexual advances), and sexual victimization. Results indicated positive bivariate correlations among all study variables. Path analyses showed that mild forms of sexual objectification (body evaluation) mediated the link between the frequency of alcohol use and more extreme forms of sexual objectification (unwanted advances). Furthermore, the combined effect of sexual objectification (body evaluation and unwanted advances) mediated the link between alcohol use (frequency and quantity) and sexual victimization. The current findings are among the first to evaluate sexual objectification as a mechanism in the link between alcohol use and sexual victimization. Results suggest that efforts to prevent alcohol-related sexual violence may benefit from addressing sexual objectification.
Quality of life and spiritual well being in individuals with HIV/AIDS

Current study evaluates the quality of life and spiritual well-being in HIV/Aids people. Two hundred HIV individuals were taken as samples (111 women and 89 men), aged between 19 to 67 years old, 143 symptomatic/Aids and 57 asymptomatic, 62.5% had taken anti-retroviral therapy. Results point to a significant correlation between the quality of life (WHOQOL-HIV bref) and spiritual well being (SWB). The spiritual, religiosity and personal beliefs and the subscale religious well being had the highest scores. Significant correlations were obtained in symptomatic/Aids group between quality of life concerning physical, social relationship and spiritual, religiosity and personal beliefs with the religious well-being, the existential well being and the spiritual well-being. The importance of the variables religiosity and spirituality within the resilience and health protection process was also discussed. Discussing health protection in research, in psychologist’s interventions and in health public policies should be enhanced.
Aligning Overlapping Image Sequences by the Combination of Feature-Based and Direct Methods

A new method for the spatio-temporal alignment of overlapping image sequences from static cameras is presented in this paper. This method first estimates the initial spatial transformation by registering the background images. Then the temporal transformation is estimated in a feature-based manner, using the Hausdorff distance and linear regression. The parameters of the estimated spatio-temporal transformation are then refined by a direct method to give a more precise result. The combination of both feature-based estimation and direct method can cope with large displacements in the temporal domain and provide high spatial alignment accuracy as well.
Open Access Research Article Development of a Highly Metastatic Model That Reveals a Crucial Role of Fibronectin in Lung Cancer Cell Migration and Invasion

Background: The formation of metastasis is the most common cause of death in patients with lung cancer. A major implement to understand the molecular mechanisms involved in lung cancer metastasis has been the lack of suitable models to address it. In this study, we aimed at establishing a highly metastatic model of human lung cancer and characterizing its metastatic properties and underlying mechanisms. Methods: The human lung adeno-carcinoma SPC-A-1 cell line was used as parental cells for developing of highly metastatic cells by in vivo selection in NOD/SCID mice. After three rounds of selection, a new SPC-A-1sci cell line was established from pulmonary metastatic lesions. Subsequently, the metastatic properties of this cell line were analyzed, including optical imaging of in vivo metastasis, immunofluorescence and immunohistochemical analysis of several epithelial mesenchymal transition (EMT) makers and trans-well migration and invasion assays. Finally, the functional roles of fibronectin in the invasive and metastatic potentials of SPC-A-1sci cells were determined by shRNA analysis. Results: A spontaneously pulmonary metastatic model of human lung adeno-carcinoma was established in NOD/ SCID mice, from which a new lung cancer cell line, designated SPC-A-1sci, was isolated. Initially, the highly metastatic behavior of this cell line was validated by optical imaging in mice models. Further analyses showed that this cell line exhibit phenotypic and molecular alterations consistent with EMT. Compared with its parent cell line SPC-A-1, SPC-A-1sci was more aggressive in vitro, including increased potentials for cell spreading, migration and invasion. Importantly, fibronectin, a mesenchymal maker of EMT, was found to be highly expressed in SPC-A-1sci cells and down-regulation of it can decrease the in vitro and in vivo metastatic abilities of this cell line. Conclusions: We have successfully established a new human lung cancer cell line with highly metastatic potentials, which is subject to EMT and possibly mediated by increased fibronectin expression. This cell line and its reproducible s.c. mouse model can further be used to identify underlying mechanisms of lung cancer metastasis. Background According to the World Health Organization, lung cancer is responsible for more than 1.3 billion deaths worldwide annually. Despite advances in the treatment of primary tumours, recurrence and metastasis are the most common cause of death in patients with lung cancer. The current poor understanding of the molecular mechanisms
A Research Communication Brief: Gluten Analysis in Beef Samples Collected Using a Rigorous, Nationally Representative Sampling Protocol Confirms That Grain-Finished Beef Is Naturally Gluten-Free

Knowing whether or not a food contains gluten is vital for the growing number of individuals with celiac disease and non-celiac gluten sensitivity. Questions have recently been raised about whether beef from conventionally-raised, grain-finished cattle may contain gluten. To date, basic principles of ruminant digestion have been cited in support of the prevailing expert opinion that beef is inherently gluten-free. For this study, gluten analysis was conducted in beef samples collected using a rigorous nationally representative sampling protocol to determine whether gluten was present. The findings of our research uphold the understanding of the principles of gluten digestion in beef cattle and corroborate recommendations that recognize beef as a naturally gluten-free food.
Consensus of Multi-Agent Systems by Distributed Event-Triggered Control

Abstract In this paper, the consensus problem for multi-agent systems with general linear dynamics is studied. A novel event-triggered control scheme with some desirable features, including distributed, asynchronous and independent, is proposed. It is shown that consensus of the controlled multi-agent system can be reached asymptotically. The feasibility of the event-triggered strategy is further verified by the exclusion of both singular triggering and Zeno behaviors. The proposed control scheme is applied to solve a spacecraft formation flying problem. Simulations illustrate the effectiveness of the control scheme.
Green Networking : Enabling Technologies , Potentials , and Challenges

We are in the midst of a major change in mobile wireless networks. Driven by the massive number of mobileconnected devices and the constant increase in the data rates, the primary objective of wireless network operators has been to satisfy the throughput of users and maximize the network capacity. However, this has lead to an energy inefficient network design. Our goal in this paper is to discuss the potential solutions and key enabling technologies that will facilitate network operators introduce power savings and improve energy efficiency in next-generation wireless networks. Specifically, we focus on the energy efficiency aspects of massive multiple-input multiple output systems (or also referred to as Large-Scale Antenna Systems), millimeter-wave communications, and dense deployment of small cells. With the goal of an energy-efficient network design, we identify the recent advances, quantify how much gain can be achieved, and present a comprehensive summary of open problems in these areas.

Two Active Forms of Zymomonas mobilis Levansucrase

Fructansucrases, members of glycoside hydrolase family 68, catalyze both sucrose hydrolysis and the polymerization of fructose to β-d-fructofuranose polymers. The resulting fructan polymers are distinguished by the nature of the glycosidic bond: inulin (β-(2–1)-fructofuranose) and levan (β-(2–6)-fructofuranose). In this study we demonstrate that Zymomonas mobilis levansucrase exists in two active forms, depending on the pH and ionic strength. At pH values above 7.0, the enzyme is mainly a dimer, whereas at pH values below 6.0, the protein forms well ordered microfibrils that precipitate out of the solution. These two forms are readily interchangeable simply by changing the pH. Surprisingly the manner in which the enzyme is arranged strongly affects its product specificity and kinetic properties. At pH values above 7.0, the activity of the enzyme as a dimer is mainly sucrose hydrolysis and the synthesis of short fructosaccharides (degree of polymerization, 3). At pH values below 6.0, in its microfibril form, the enzyme catalyzes almost exclusively the synthesis of levan (a degree of polymerization greater than 20,000). This difference in product specificity appears to depend on the form of the enzyme, dimer versus microfibril, and not directly on the pH. Images made by negative stain transmission electron microscopy reveal that the enzyme forms a very ordered structure of long fibrils that appear to be composed of repeating rings of six to eight protein units. A single amino acid replacement of H296R abolished the ability of the enzyme to form microfibrils with organized fibril networks and to synthesize levan at pH 6.0.
Achiasmy: Male Fruit Flies Are Not Ready to Mix

Maintenance of the chromosomal copy number over generations and recombination between homologous chromosomes are hallmarks of meiotic cell division. This genetic exchange that take place during gamete formation leads to genetic diversity, the main driving force behind natural selection. Formation of chiasmata, the physical link between homologous chromosomes during meiosis, is a requisite for recombination. In addition, chiasmata also aid in proper segregation of homologous chromosomes and has a major impact on reproductive fitness. Given these facts it is intriguing that many insect species have forgone the need for genetic exchange between homologous chromosomes during meiosis. Geneticists for several decades knew that meiotic crossover and recombination is absent in Drosophila males and some female lepidopterans, a condition termed achiasmy. However, a good understanding of the mechanisms that cause achiasmy and the evolutionary benefits of achiasmy is currently lacking. In this article we will discuss possible genetic and molecular basis of achiasmy in male Drosophila.

Tradução, adaptação e estudo da validade de construto da Scale of Ethnocultural Empathy

Ethnocultural Empathy is a construct that helps to understand phenomena encompassing cultural issues, respect to ethnocultural differences, and affective and social-moral development. The present study aimed to translate, to adapt and to assess the construct validity of the Scale of Ethnocultural Empathy – SEE for use in Brazil. A total of 350 undergraduate students resident in the city of Juazeiro, BA (Brazil) participated of this study. They answered to the modified version of the SEE – which was called in Portuguese Escala de Empatia Etnocultural – EEE, and a questionnaire assessing socio-demographic characteristics. A factor analysis of 26 items suggested that a three-factor solution provided the best fit to the data. The overall internal consistency of the SEE (general level of ethnocultural empathy) was good (α = .808). Taken as a whole, the psychometric properties of the Scale of Ethnocultural Empathy are suitable to assess the Ethnocultural Empathy and demonstrate that the SEE is an important research tool in future studies.
Improving Gemcitabine-Mediated Radiosensitization Using Molecularly Targeted Therapy: A Review

In the last three decades, gemcitabine has progressed from the status of a laboratory cytotoxic drug to a standard clinical chemotherapeutic agent and a potent radiation sensitizer. In an effort to improve the efficacy of gemcitabine, additional chemotherapeutic agents have been combined with gemcitabine (both with and without radiation) but with toxicity proving to be a major limitation. Therefore, the integration of molecularly targeted agents, which potentially produce less toxicity than standard chemotherapy, with gemcitabine radiation is a promising strategy for improving chemoradiation. Two of the most promising targets, described in this review, for improving the efficacy of gemcitabine radiation are epidermal growth factor receptor and checkpoint kinase 1.
Improper cause-of-death statements by specialty of certifying physician: a cross-sectional study in two medical centres in Taiwan

Objective To determine the frequency of various types of improper cause-of-death (COD) statements reported on death certificates and whether the frequency differed by specialty of the certifying physician. Design Cross-sectional descriptive study. Setting 2 medical centres in Tainan, Taiwan. Participants A total of 2520 death certificates issued by 230 physicians. Main outcome measures 4 types of improper COD statements based on the criteria of correctness of the COD causal sequence and the level of specificity of underlying COD selected. Results Of 2520 death certificates analysed, 502 (19.9%) had at least one type of improper COD statement. However, only 235 (9.3%) sustained major errors, that is, 91 (3.6%) reported incorrect causal sequence and 144 (5.7%) reported only mechanism(s) of death (such as respiratory failure, heart failure, sepsis and acidosis). The improper reporting rate was highest among nephrologists (53%, 24/45), followed by infectious diseases physicians (45%, 29/65) and was lowest among oncologists (6%, 57/995). Conclusions About one-fifth issued death certificates sustained improper COD statements and only one-tenth had noteworthy errors that would threaten the quality of COD statistics. The frequency varied by specialty of the certifying physician because physicians in different specialties manage different types of diseases and conditions with contrasting complexities in terms of determining the causal sequence and specificity of COD statements.
“Diversity,” immigration, and the new American multi-racial hierarchy

Purpose – This paper aims to analyze the new multi-racial hierarchy in the USA. The authors propose that despite increasing diversity, a multi-racial hierarchy of privilege and disadvantage continues to exist. Due to the history of anti-Black discrimination and stereotyping in the USA, employers prefer native and immigrant non-Blacks to native and immigrant Blacks, and use non-Blacks to claim organizational diversity success. Design/methodology/approach – The authors propose that a multi-racial hierarchy, ordered as Whites, Non-White Non-Blacks, and Collective Blacks now exists, and use history, relevant theory, existing research, and government data to support their ideas. Findings – Evidence suggests that despite increased diversity, Whites remain most privileged, Blacks least privileged, and Asians and Hispanics tend to comprise the middle of the hierarchy. Even in organizations that are “diverse,” a multi-racial hierarchy results in different compensation, promotion, and layoff rates and differential .
Snail and E47 repressors of E-cadherin induce distinct invasive and angiogenic properties in vivo

The transcription factors Snail and E47 are direct repressors of E-cadherin, with both inducing a full epithelial-mesenchymal transition and invasive behaviour in vitro when expressed in the prototypic epithelial MDCK cell line. The role of these repressors in the invasive process and in other tumorigenic properties is, nevertheless, still poorly understood. However, organotypic cultures and in vivo transplantation assays indicate that cells expressing MDCK-Snail and MDCK-E47 exhibit significant differences. MDCK-Snail cells have a higher infiltrative potential than MDCK-E47 cells. Interestingly, both cell types induce angiogenesis of the host stromal tissue in transplantation assays, but this property is greatly enhanced in transplants of MDCK-E47 cells. Xenografted tumours induced in nude mice also show signs of strong angiogenic potential, again markedly increased in tumours induced by MDCK-E47 which exhibit a higher vessel density and proliferation rate than those induced by MDCK-Snail cells. These results suggest differential roles for Snail and E47 E-cadherin repressors in tumour progression where Snail is implicated in promoting the initial invasion and E47 plays an active role in tumour cell growth by promoting angiogenesis.
Population and Evolutionary Dynamics based on Predator–Prey Relationships in a 3D Physical Simulation

Recent studies have reported that population dynamics and evolutionary dynamics, occurring at different time scales, can be affected by each other. Our purpose is to explore the interaction between population and evolutionary dynamics using an artificial life approach based on a 3D physically simulated environment in the context of predator–prey and morphology–behavior coevolution. The morphologies and behaviors of virtual prey creatures are evolved using a genetic algorithm based on the predation interactions between predators and prey. Both population sizes are also changed, depending on the fitness. We observe two types of cyclic behaviors, corresponding to short-term and long-term dynamics. The former can be interpreted as a simple population dynamics of Lotka–Volterra type. It is shown that the latter cycle is based on the interaction between the changes in the prey strategy against predators and the long-term change in both population sizes, resulting partly from a tradeoff between their defensive success and the cost of defense.
Investigating Metrics to Build a Benchmark Tool for Complex Event Processing Systems

Despite companies' demand for data streams processing systems to handle large volumes of flowing data, we did not find many software to assess these sort of systems. In fact, up to date, there are few papers proposing metrics to evaluate these systems or describing software for benchmarks. Most of the papers focus on metrics such as throughput, latency and memory consumption. However, there are other metrics, which system administrators and users should consider, such as information latency, the correctness of results, adaptability on different workloads and others. Therefore, in this paper, we summarized some key metrics used to assess systems for processing online data streams. In addition, we discuss three benchmark tools found in the literature to assess this type of system. At the end of this paper, we propose a new benchmark tool for complex event processing distributed systems called B2-4CEP, which incorporate the metrics described in this paper.
Lexicographical Manipulations for Correctly Computing Regular Tetrahedralizations With Incremental Topological Flipping

Edelsbrunner and Shah have proven that incremental topological ﬂipping works for constructing a regular triangulation for a ﬁnite set of weighted points in d − dimensional space. This paper describes the lexicographical manipulations employed in a recently completed implementation of their method for correctly computing 3-dimensional regular triangulations. At the start of the execution of this implementation a regular triangulation for the vertices of an artiﬁcial cube that contains the points is constructed. Throughout the execution the vertices of this cube are treated in the proper lexicographical manner so that the ﬁnal triangulation is correct.
