The contextual role of subjective age in the chronological age/absenteeism relationship in blue and white collar teams

ABSTRACT Organizations in the twenty-first century face the challenges of an increasingly ageing workforce, which have an effect on organizational health and productivity. As chronological age has shown to be an insufficient indicator of employees’ health and, in particular, absenteeism, we apply the subjective age concept (i.e., how old an employee feels) at the team-level to explain the average chronological age/average short-term absenteeism relationship. We develop a theoretical framework for underlying processes, combining the subjective age research with the socioemotional selectivity theory and team contagion processes. We test our predictions in a time-lagged team-level sample of 1,015 teams with 12,926 employees to find a significant interactive effect of average chronological age and average subjective age on average short-term absenteeism in teams. The relationship is negative and significant when average subjective age is low. Under high-average subjective age, the relationship is non-significant. Furthermore, this interactive effect (average chronological age/average subjective age) is moderated by job type (white versus blue collar) in the form of a three-way interaction, indicating that the effect is only significant among white collar teams. We hope to enrich the theoretical debate on age and absenteeism and provide organizations with a new perspective on ageing work teams.
Interactants and activities on Facebook, Instagram, and Twitter: Associations between social media use and social adjustment to college

ABSTRACT Research shows use of social media (SM) has important implications for college adjustment. However, most studies only focused on Facebook and did not attend to specific use patterns. Drawing on the activity-audience framework of social media use and literature of college adjustment, we examined the associations between use of Facebook, Instagram, and Twitter and college social adjustment. Regression and cluster analyses of survey data from 257 undergraduates (Mage = 19.48) showed that SM interactants had stronger and more consistent associations with social adjustment than did activities. Using Facebook and Instagram with on-campus friends and family were related to better social adjustment; using Instagram with strangers was related to poorer adjustment. Students who frequently used all three SM to interact with off-campus friends were less adjusted than those who rarely used the platforms to interact with strangers. Some associations were moderated by SM activities. Implications of college students’ development in the digital age are discussed.
Recent Advances in the Design of Water Based-Flame Retardant Coatings for Polyester and Polyester-Cotton Blends

Over the last ten years a new trend of research activities regarding the flame retardancy of polymeric materials has arisen. Indeed, the continuous search for new flame retardant systems able to replace the traditional approaches has encouraged alternative solutions, mainly centred on nanotechnology. In this context, the deposition of nanostructured coatings on fabrics appears to be the most appealing and performance suitable approach. To this aim, different strategies can be exploited: from the deposition of a single monolayer consisting of inorganic nanoparticles (single-step adsorption) to the building-up of more complex architectures derived from layer by layer assembly (multi-step adsorption). The present paper aims to review the application of such systems in the field of polyester and polyester-cotton blend fabrics. The results collated by the authors are discussed and compared with those published in the literature on the basis of the different deposition methods adopted. A critical analysis of the advantages and disadvantages exhibited by these approaches is also presented.
Evolution of code clone ratios throughout development history of open-source C and C++ programs

A code clone is a fragment of code which is duplicated throughout the source code of a project. Code clones have been shown to make a project less maintainable because all code clones will share potential bugs and problems. Unlike other code clone research, this study analyzes the code clone ratios over the entire development lifetime of three open-source projects written in C/C++ to understand code clone growth in software over development and potential developer habits which could affect this growth. The study utilizes CCFinderX and Git to detect clone metrics across development history. The results from each project show very low, stable ratios across development history, with the code clone ratios only fluctuating greatly during the beginning of development mostly and very little refactoring occurring. This study goes further into the potential cause of low ratios and different fluctuations at different periods of development.
Abstract interpretation-based approaches to Security - A Survey on Abstract Non-Interference and its Challenging Applications

In this paper we provide a survey on the framework of abstract non-interference. In particular, we describe a general formalization of abstract non-interference by means of three dimensions (observation, protection and semantics) that can be instantiated in order to obtain well known or even new weakened non-interference properties. Then, we show that the notions of abstract non-interference introduced in language-based security are instances of this more general framework which allows to better understand the different components of a non-interference policy. Finally, we consider two challenging research fields concerning security where abstract non-interference seems a promising approach providing new perspectives and new solutions to open problems: Code injection and code obfuscation.
What Can Neuroimaging Tell Us About the Mind?

Psychologists interested in the workings of the mind may wonder whether brain-imaging data can provide insight regarding cognitive mechanisms. Here we consider one means through which imaging can inform cognitive theory: reverse inference, wherein activations in well-characterized neural structures serve as markers for the engagement of particular cognitive processes. To illustrate this approach, we review brain-imaging evidence regarding the organization of cognitive and linguistic processes in the prefrontal cortex, which indicates that phonological (speech-sound-based) and semantic (meaning-based) processing are consistently associated with topographically distinct patterns of activity in the left inferior prefrontal cortex. We then illustrate how this finding of regional differentiation has provided useful guidance for understanding the cognitive processes supporting memory encoding and retrieval. We conclude with caveats that highlight some of the limitations of the reverse-inference approach.
in Human Head and Neck Xenograft Tumors 2 Prostaglandin E Direct Evidence for a Role of Cyclooxygenase 2-derived Updated

Both nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase (COX) 2-selective inhibitors such as celecoxib are being reported as having potent anticancer activity in laboratory models. Several reports have suggested that the mechanism of action of these agents in reducing tumor volume/burden is unrelated to their inhibition of prostaglandin synthesis. Many in vitro reports use supraphysiological concentrations of these drugs to demonstrate COX-independent activities on apoptosis or proliferation. In vivo, most murine tumor models express COX-2 only in the vasculature and stroma, unlike human tumors that also express COX-2 in the tumor cells. In general, these models have the limitation of having no measurable, COX-2-derived, prostaglandins, the inhibition of which correlates with antitumor efficacy. We report here that 1483 human head and neck xenograft tumors express COX-2 similar to the pattern observed in human solid tumors and that COX-2 activity produces high levels of prostaglandin E2 (PGE2). Inhibition of COX-2 by celecoxib resulted in loss of intratumor PGE2 levels and reduced tumor growth in a dose-dependent manner. In contrast, a selective COX-1 inhibitor, SC-560, did not measurably reduce tumor prostaglandin levels or tumor growth despite the presence of COX-1 in the host and tumor cells. Celecoxibtreated tumors showed reduced proliferation and increased apoptosis of both tumor and stromal cells compared with vehicle controls. Specific inhibition of PGE2 activity by a neutralizing antibody mimicked the reduced tumor growth observed after celecoxib treatment, suggesting growth is PGE2 mediated. These data indicate that a major antitumor mechanism of action of celecoxib is inhibition of COX-2-derived prostaglandins, particularly PGE2, and suggest celecoxib as a novel therapeutic agent for human head and neck cancer.
Body Worn Cameras, Procedural Justice, and Police Legitimacy: A Controlled Experimental Evaluation of Traffic Stops

Abstract Police legitimacy is generally regarded as a view among community members that police departments play an appropriate role in implementing rules governing public conduct. Placing body worn cameras (BWCs) on police officers has been suggested as a potentially important response to police legitimacy crises. We use a rigorous controlled quasi-experimental evaluation to test the impact of BWCs on citizen perceptions of procedural justice and police legitimacy during traffic stops in Turkey. Relative to stops by officers without BWCs, we find that motorists stopped by officers with BWCs reported improved perceptions of procedural justice in the encounter and perceptions of legitimacy of traffic officers and the police more generally. Supplementary analyses suggest that the perceived improvements in police legitimacy were entirely driven by perceived enhancements in procedural justice during the traffic stop encounter. These findings suggest that body camera technology help ensure procedurally just encounters and improve public perceptions of police legitimacy.
Teen Athletes: Facebook, Self Esteem and Self Perception

In this research we examined the social network use, and more precisely, the use of Facebook, and the impact on psychological factors such as self esteem and overall self perception. The participants were 87 teen athletes from sports such as basketball, volleyball and football. Results indicated that self esteem played a major role in the behaviour of children. Six Facebook factors were analysed: behavioral intention, satisfaction, using applications, time waste, social connection and social surfing. Finally the research pointed out where is the connection between social surfing, using applications, self esteem, self perception of athletic ability and self perception of physical appearance.
Please , provide the mansucript number ! ) Loss Models with Dependent Service Times

Effective approximations are developed for the blocking probability in a general stationary loss model with dependence among successive service times as well as among successive interarrival times by exploiting heavy-traffic limits for the steady-state number of busy servers in the associated infinite-server model with the same arrival and service processes. In addition, a new heavy-traffic approximation is developed for the long-run proportion of time that all servers are busy. These new approximations are then combined to develop effective approximations for the separate blocking probabilities of individual arrival streams in multi-class loss models.
Which configuration option should I change?

Modern software often exposes configuration options that enable users to customize its behavior. During software evolution, developers may change how the configuration options behave. When upgrading to a new software version, users may need to re-configure the software by changing the values of certain configuration options. This paper addresses the following question during the evolution of a configurable software system: which configuration options should a user change to maintain the software's desired behavior? This paper presents a technique (and its tool implementation, called ConfSuggester) to troubleshoot configuration errors caused by software evolution. ConfSuggester uses dynamic profiling, execution trace comparison, and static analysis to link the undesired behavior to its root cause - a configuration option whose value can be changed to produce desired behavior from the new software version. We evaluated ConfSuggester on 8 configuration errors from 6 configurable software systems written in Java. For 6 errors, the rootcause configuration option was ConfSuggester's first suggestion. For 1 error, the root cause was ConfSuggester's third suggestion. The root cause of the remaining error was ConfSuggester's sixth suggestion. Overall, ConfSuggester produced significantly better results than two existing techniques. ConfSuggester runs in just a few minutes, making it an attractive alternative to manual debugging.
Ethno-theatre: Exploring a narrative intervention for trafficking survivors

ABSTRACT In the age of positivist research inquiry, evidence-based research is gaining momentum. Quantitative data supporting theoretical reasoning is allowing several advances in the Western social work curriculum and practice. However, with increasing emphasis on quantifiable significance of research outcomes, several issues and populations are being underrepresented in social work arena. Historically, the Eastern social work tradition has embraced multiple research approaches from various social science disciplines. Deriving from an anthropological approach, in this article ethno-theatre is used as a tool of narrative therapy for victims of human trafficking to assess its impact of witnessing lived experience narrated by trained actors. Results of this study reveal that staging victim narratives for girls who were sex-trafficked as minors create a cathartic environment of comfort where victims feel positive, important and empowered. This model hypothesizes that ethno-theatre operated within the framework of narrative therapy can expedite the process of recreating victim stories to build a positive social environment in the process of empowering survivors of human trafficking.
Like a Dog in THE Manger: Mobilizations in Times of Extractive Capitalism: The Cases of Romania and the Czech Republic

In the middle of the heated debate on how to reverse climate change, some countries in Eastern Europe are returning to extractive industries and the exploitation of natural resources to finance their national budgets. The paper looks at mobilization in one locality in Romania and the Czech Republic and investigates the radically different pattern of mobilization in these two otherwise similar areas. Whereas in many Romanian cities affected by this economic "transformation," citizens have protested against it, as in Câmpeni with regard to the Roșia Montană gold mining project, in the Czech Republic, however, the extension of coal extraction was hardly opposed by the general population, with the exception of environmental groups. Using critical political economy approach, the paper explores the interaction between the economic changes, politics, and citizens' reactions and argues that the difference in outcome can be explained by the configuration of the economic organization, and the dominant "social blocks" that sustain it, in each of the areas considered.
Reflective journal writing of undergraduate students enrolled in sex education in Hong Kong

ABSTRACT The purpose of this study was to investigate the impact of reflective journal writing on the thinking process and academic performance of local undergraduates in their course on sexual health and human sexuality. A two-group quasi-experimental design was used to analyze students’ reflective journals in terms of learning gains on sex education. The data for analysis were extracted from the 159 specific phrases which were categorized and retrieved through NVivo analysis of the students’ reflective journals. The comments about thinking were the largest number of responses. The correlation between academic performance and self-reflection was significant; the F value (0.125, 0.025) = 4.96, p value was 0.029 which is significant at p < 0.05. There is a relationship between reflection and course grade in the context of sex education.
In the wake of a terrorist attack, do Americans’ attitudes toward Muslims decline?

When a terrorist attack occurs, a natural response may be increased public concern about terrorism. But when a self-described Muslim perpetrates a terrorist attack, do negative attitudes toward Muslims also increase? If so, is this effect conditional on the nature of people’s past personal experiences with Muslims? We present natural experiment data based on a 2015 web-based survey of 2105 non-Muslims in the US, a survey that happened to span the terrorist attacks in Paris on 13 November and San Bernardino on 2 December. We thus test Americans’ feelings toward Muslims immediately before and after both an international and a domestic terrorist attack. We find that, although the attacks significantly affected Americans’ concerns about radicalism both in the US and abroad, they did not negatively affect Americans’ thermometer feelings toward Muslims in the aggregate—a null finding conditioned only slightly by the nature of past personal experiences with Muslims.
Involvement of p54(nrb), a PSF partner protein, in DNA double-strand break repair and radioresistance

Mammalian cells repair DNA double-strand breaks (DSBs) via efficient pathways of direct, nonhomologous DNA end joining (NHEJ) and homologous recombination (HR). Prior work has identified a complex of two polypeptides, PSF and p54(nrb), as a stimulatory factor in a reconstituted in vitro NHEJ system. PSF also stimulates early steps of HR in vitro. PSF and p54(nrb) are RNA recognition motif-containing proteins with well-established functions in RNA processing and transport, and their apparent involvement in DSB repair was unexpected. Here we investigate the requirement for p54(nrb) in DSB repair in vivo. Cells treated with siRNA to attenuate p54(nrb) expression exhibited a delay in DSB repair in a γ-H2AX focus assay. Stable knockdown cell lines derived by p54(nrb) miRNA transfection showed a significant increase in ionizing radiation-induced chromosomal aberrations. They also showed increased radiosensitivity in a clonogenic survival assay. Together, results indicate that p54(nrb) contributes to rapid and accurate repair of DSBs in vivo in human cells and that the PSF·p54(nrb) complex may thus be a potential target for radiosensitizer development.
Induction of 1,2-Dicarbonyl Compounds, Intermediates in the Formation of Advanced Glycation End-Products, during Heat-Sterilization of Glucose-Based Peritoneal Dialysis Fluids

Objective To study the presence of 1,2-dicarbonyl compounds in peritoneal dialysis (PD) fluids, their concentration in effluents with increasing dwell time, and their role in the formation of advanced glycation end-products (AGEs). Measurements Dicarbonyl compounds in heat- and filter-sterilized PD fluids were quantified by reverse-phase high performance liquid chromatography (HPLC) after derivatization to dimethoxyquinoxaline derivatives. Kinetics of the in vitro formation of AGEs upon incubation of 1,2-dicarbonyl compounds or PD fluids with albumin, with or without aminoguanidine, were measured by AGE fluorescence (excitation/emission wavelengths of 350 nm/430 nm). Patients AGEs and dicarbonyl compounds were measured in effluents collected from standardized 4-hour dwells from 8 continuous cycling peritoneal dialysis patients. Results In PD fluids, 3-deoxyglucosone (3-DG) has been identified as the major dicarbonyl compound formed during the process of heat sterilization. The process also formed glyoxal (GO) and methylglyoxal (MGO), with the amount of 3-DG being approximately 25 – 60 times higher than GO and MGO. When incubated with albumin, the identified 1,2-dicarbonyl compounds rapidly formed AGEs. The formation of AGEs was more pronounced in conventional heat-sterilized PD fluids compared with filter-sterilized PD fluids, and was completely inhibited by aminoguanidine. In effluents, the concentration of MGO, GO, and 3-DG decreased with increasing dwell time, with a concomitant increase in AGE fluorescence. Conclusions The dicarbonyl compounds 3-DG, MGO, and GO are potent promoters of AGE formation. The presence of these and possibly other dicarbonyl compounds formed during heat sterilization of glucose-based PD fluids is, to a large extent, responsible for the in vitro AGE formation by these fluids, as evidenced by the speed of AGE formation in PD fluids and the complete inhibition by aminoguanidine. Because 3-DG, MGO, and GO are rapidly cleared from PD fluids during dialysis, these compounds may contribute to the in vivo AGE formation in PD patients.
