Examining the quality of social support messages produced face-to-face and in computer-mediated communication: The effects of hyperpersonal communication

ABSTRACT The hyperpersonal communication model was used to investigate the implications of the reduced social cues in computer-mediated communication (CMC) for the production of social support messages. Participants were randomly assigned to interact with a confederate seeking help about a problem for which the confederate was or was not responsible. The interactions took place either face-to-face or in one of two CMC conditions. The results were partially consistent with the intensification effect proposed in the hyperpersonal model. Participants evaluated the confederate most negatively, but produced the highest quality support messages, in the CMC condition with visual anonymity followed by the CMC condition and face-to-face condition. Participants’ evaluations of the confederate were also influenced by the confederate’s responsibility for their problem.
The dependence of star formation history and internal structure on stellar mass for 105 low‐redshift galaxies

We study the relations between stellar mass, star formation history, size and internal structure for a complete sample of 122 808 galaxies drawn from the Sloan Digital Sky Survey. We show that low-redshift galaxies divide into two distinct families at a stellar mass of 3 x 10 1 0 M O . Lower-mass galaxies have young stellar populations, low surface mass densities and the low concentrations typical of discs. Their star formation histories are more strongly correlated with surface mass density than with stellar mass. A significant fraction of the lowest-mass galaxies in our sample have experienced recent starbursts. At given stellar mass, the sizes of low-mass galaxies are lognormally distributed with dispersion σ(In R 5 0 ) ∼0.5, in excellent agreement with the idea that they form with little angular momentum loss through cooling and condensation in a gravitationally dominant dark matter halo. Their median stellar surface mass density scales with stellar mass as μ * M * 0.54, suggesting that the stellar mass of a disc galaxy is proportional to the three halves power of its halo mass. All of this suggests that the efficiency of the conversion of baryons into stars in low-mass galaxies increases in proportion to halo mass, perhaps as a result of supernova feedback processes. At stellar masses above 3 x 10 1 0 M O . , there is a rapidly increasing fraction of galaxies with old stellar populations, high surface mass densities and the high concentrations typical of bulges. In this regime, the size distribution remains lognormal, but its dispersion decreases rapidly with increasing mass and the median stellar mass surface density is approximately constant. This suggests that the star formation efficiency decreases in the highest-mass haloes, and that little star formation occurs in massive galaxies after they have assembled.
Do it Helps SMEs Gain Better Performance: A Conceptual Analysis on RBV Theory

Nowadays, competition is everywhere in the business environment. The survival of Small and medium-sized enterprises (SMEs) depend on their ability to take full advantage of the resources available. Prior research had identified that IT is an important resource to the success of the firms. However, despite the common consensus that IT influences firm’s performance, results of previous studies on the effect of IT resources on firm’s performance are often inconsistent. Given these inconsistent results, it is unclear whether any direct effect exists between IT resources in organizations and their firm’s performance. For that reason, several authors highlighted the need for more research to investigate the impact of IT adoption on the firm’s performance. In response to this, this conceptual paper attempts to analyze relevant literatures on whether IT investment would help firms gain better performance. Understanding whether and how IT has affected firm’s performance is an important research issue as it allows the firms to know the value of IT investment and whether such innovation is worth to be adopted. Grounding in RBV theory, this study concluded that the combination of IT assets and IT capabilities (IT infrastructure) provides competitive advantage to the firm. This study also suggested that SMEs that adopt IT would perform better than those that do not adopt IT. This conceptual analysis is hoped to consolidate the body of knowledge in the area and significant to the researchers as it directs to the hypotheses development for future research.
Impact of Multiple Intelligence Based Intervention on Cognitive Abilities of Students

As an enlightening process, the principal and global intent of education is to enhance students’ cognitive abilities. Cognitive abilities induce progressive attainment and retention of learning skills that enable children to apply the attained information. Cognitive abilities can be improved by providing the right training to children. An in-depth longitudinal study was conducted to analyze the impact of educational intervention based on Gardner’s multiple intelligence on the cognitive abilities of the respondents. Cluster sampling was followed to extract a sample including 3500 school going boys and girls aged between 11-14 years in India. The sample was primarily categorized into experimental and control groups. Both the groups were assessed in terms of their intelligence quotient, focus factor, decision making ability, creative quotient, cognitive capacity and estimation level thrice during the timeline of 12 months. Standardized cognitive ability assessment and multiple intelligence assessment were administered on them. Experimental group availed intervention whereas the control group was excluded from intervention. Intervention was provided in form of task-sheets based on the age and respective dominant multiple intelligence of each student. Eventually, a significant surge was notified in the cognitive abilities of experimental group while there was no such noticeable change in the cognitive abilities of control group. Therefore, it was concluded that the cognitive abilities of the children can be enhanced drastically if the educational instructions are imparted through their respective dominant intelligence. Hence, the educational system can become highly productive to bestow inevitable improvement in the development of cognitive abilities among students.
Serum Properdin in Tumor-bearing Mice . I . Comparison with Natural and Immune Antibodies *

Growth of a transplanted, isologous mammary carcinoma resulted in depressed titers of serum properdin and Shigella parodysenteriae antibody in mice. This tumor had no apparent deleterious influence on natural antisheep hemagglutinins. Tumor antigen preparations did not produce these effects. The likelihood that these alterations in immune response are secondary rather than direct effects is suggested by their con stant association in time with the preterminal state and by the observation that properdin levels could be preserved by zymosan injections without influencing tumor growth.
Automatic Enrollment, Employer Match Rates and Employee Compensation in 401(K) Plans

This study uses restricted-access employer-level microdata from the National Compensation Survey to examine the relationship between automatic enrollment and employee compensation. By boosting plan participation, automatic enrollment has the potential to increase employer defined contribution plan costs as previously unenrolled workers receive matching contributions. Using cross-sectional variation in employer compensation costs and the automatic enrollment provision within firms sponsoring DC plans, we examine differences in compensation between those with and without the provision. A significant negative correlation exists between the generosity of the employer match structure and the automatic enrollment provision. However, we find no evidence that total compensation costs or DC costs differ between firms with and without automatic enrollment, and no evidence that DC costs crowd out other forms of compensation.
The Current Obesity Epidemic: Unravelling the Evolutionary Legacy ofAdipose Tissue

The evolution of organisms is shaped by the selective pressures to which they are subject. Selective pressures produce a trade-off between costs and benefits that ultimately influences the fitness of the whole organism. Classically, it has been pointed out that food intake is allocated between its use for physiological functions and its store for future utilization. Moreover, it is accepted that the perfect survivor must be able to eat and store as many calories as possible when food is available as a buffer against periods of scarcity. Thus, during evolution the ability to overeat and store the extra energy in specialized tissues has conferred an advantage. The strategy is known as the thrifty genotype (TG). The primary form in which chemical energy is stored in the body is fat. The aim of this article is to review the participation of adipose tissue in the TG. The role of fat within an evolutionary framework is explored. Moreover, the evolutionary purposes of the different adipose depots are analyzed, suggesting that each depot could have evolved in order to develop different functions. Finally, the contribution of the TG to the current obesity epidemic is questioned.
On differentiating ground clutter and insect echoes from Doppler weather radars using archived data

Abstract. Normally wind measurements from Doppler radars rely on the presence of rain. During fine weather, insects become a potential radar target for wind measurement. However, it is difficult to separate ground clutter and insect echoes when spectral or polarimetric methods are not available. Archived reflectivity and velocity data from repeated scans provide alternative methods. The probability of detection (POD) method, which maps areas with a persistent signal as ground clutter, is ineffective when most scans also contain persistent insect echoes. We developed a clutter detection method which maps the standard deviation of velocity (SDV) over a large number of scans, and can differentiate insects and ground clutter close to the radar. Beyond the range of persistent insect echoes, the POD method more thoroughly removes ground clutter. A new, pseudo-probability clutter map was created by combining the POD and SDV maps. The new map optimised ground clutter detection without removing insect echoes.

Computer Aided Analysis of Dental Radiographic Images

This paper is a result of a fruitful cooperation between the computer science and the dental diagnosis experiences. The study presents a new approach of applying computer algorithms to radiographic images of dental implantation used for bone regeneration. We focus here only on the contribution of the computer assistance to the clinical research as the periodontal therapy is beyond the scope of this paper. The proposed system is based on a pattern recognition approach, directed to recognize density changes in the intra-bony affected areas of patients. It comprises different modules with new algorithms specially designed to treat the patients’ radiographic images more accurately. The system includes digitizing, detecting the complicated region of interest (ROI), defining reference area to correct any projection discrepancy of the follow up images, and finally to extract the distinguishing features of the ROI as a basis for determining the rate of new bone density accumulation. This study is applied to two typical dental cases for a patient who received two different operations. The results are very encouraging and more accurate than traditional techniques reported before.
Action mirroring and action understanding: an alternative account

Observed actions elicit covert motor activations in observers that, in case they were executed, would generate similar actions to the observed ones. I challenge the most popular explanation offered for these phenomena, according to which such action mirroring is generated by direct matching and serves the function of action understanding in terms of their goals. I propose that action mirroring is generated by action reconstruction via top-down emulation from action interpretation produced outside the motor system. Such action mirroring does not follow but anticipates ongoing actions and enables, beyond predictive tracking, action coordination with others. I argue that the available empirical evidence is more compatible with this alternative model than with the direct-matching account.
Intraspecific variability in the response of bloom-forming marine microalgae to changed climate conditions

Phytoplankton populations can display high levels of genetic diversity that, when reflected by phenotypic variability, may stabilize a species response to environmental changes. We studied the effects of increased temperature and CO2 availability as predicted consequences of global change, on 16 genetically different isolates of the diatom Skeletonema marinoi from the Adriatic Sea and the Skagerrak (North Sea), and on eight strains of the PST (paralytic shellfish toxin)-producing dinoflagellate Alexandrium ostenfeldii from the Baltic Sea. Maximum growth rates were estimated in batch cultures of acclimated isolates grown for five to 10 generations in a factorial design at 20 and 24°C, and present day and next century applied atmospheric pCO2, respectively. In both species, individual strains were affected in different ways by increased temperature and pCO2. The strongest response variability, buffering overall effects, was detected among Adriatic S. marinoi strains. Skagerrak strains showed a more uniform response, particularly to increased temperature, with an overall positive effect on growth. Increased temperature also caused a general growth stimulation in A. ostenfeldii, despite notable variability in strain-specific response patterns. Our data revealed a significant relationship between strain-specific growth rates and the impact of pCO2 on growth—slow growing cultures were generally positively affected, while fast growing cultures showed no or negative responses to increased pCO2. Toxin composition of A. ostenfeldii was consistently altered by elevated temperature and increased CO2 supply in the tested strains, resulting in overall promotion of saxitoxin production by both treatments. Our findings suggest that phenotypic variability within populations plays an important role in the adaptation of phytoplankton to changing environments, potentially attenuating short-term effects and forming the basis for selection. In particular, A. ostenfeldii blooms may expand and increase in toxicity under increased water temperature and atmospheric pCO2 conditions, with potentially severe consequences for the coastal ecosystem.
Derangements in simple and primitive groups

We investigate the proportion of fixed point free permutations (derangements) in finite transitive permutation groups. This article is the first in a series where we prove a conjecture of Shalev that the proportion of such elements is bounded away from zero for a simple finite group. In fact, there are much stronger results. This article focuses on finite Chevalley groups of bounded rank. We also discuss derangements in algebraic groups and in more general primitive groups. These results have applications in questions about probabilistic generation of finite simple groups and maps between varieties over finite fields.
Schema Matching Based on Attribute Values and Background Ontology

This paper focuses on the specific problem of geographic database schema matching, as a first step in an integration application. We propose, a schema matching approach based on attributes values and background ontology. We follow the intuition that comparing only schema classes is not sufficient and that there are specific class attributes in geographic database classes whose role consists in specifying the exact nature of each class instance. Their enumerated values refer to geographic concepts. We assume that it is possible to take advantage of this additional knowledge for upgrading the level of granularity of schema classifications by making it explicit in local ontologies created from each database schema that we have to match. Moreover, we propose to use external domain knowledge, namely background ontology, to improve our schema matching strategy, which implies local ontology matching. We lastly present and discus the results of two schema matching tests based on this schema matching strategy.
Application of heat stress in situ demonstrates a protective role of irradiation on photosynthetic performance in alpine plants

The impact of sublethal heat on photosynthetic performance, photosynthetic pigments and free radical scavenging activity was examined in three high mountain species, Rhododendron ferrugineum, Senecio incanus and Ranunculus glacialis using controlled in situ applications of heat stress, both in darkness and under natural solar irradiation. Heat treatments applied in the dark reversibly reduced photosynthetic performance and the maximum quantum efficiency of photosystem II (Fv/Fm), which remained impeded for several days when plants were exposed to natural light conditions subsequently to the heat treatment. In contrast, plants exposed to heat stress under natural irradiation were able to tolerate and recover from heat stress more readily. The critical temperature threshold for chlorophyll fluorescence was higher under illumination (Tc′) than in the dark (Tc). Heat stress caused a significant de-epoxidation of the xanthophyll cycle pigments both in the light and in the dark conditions. Total free radical scavenging activity was highest when heat stress was applied in the dark. This study demonstrates that, in the European Alps, heat waves can temporarily have a negative impact on photosynthesis and, importantly, that results obtained from experiments performed in darkness and/or on detached plant material may not reliably predict the impact of heat stress under field conditions.
Measurements and Determinants of Multifaceted Poverty:Absolute, Relative, and Subjective Poverty in Indonesia

The notion of ‘poverty’ is diversified and dynamic. It varies across countries with different socio-economic norms. It may also change over time even in the same society, with different stages of social and economic development. A country may be struggling with absolute poverty at the early stages of development, while it may well be more concerned with relative and/or subjective poverty as its average per-capita income increases. This article intends to conduct an exploration of multiple poverty measures by looking into the absolute, relative and subjective poverty incidence in Indonesia. Using the 2005 National Socio-Economic Survey (Susenas), we observed that there was a roughly 28 percentage-point difference in the poverty headcount ratios computed by applying absolute (14.47%) and subjective (42.03%) poverty. There were virtually no correlations among the poverty rankings in the provinces of Indonesia obtained by five poverty metrics. Results of logit model and ordered logit model estimations of the possible determinants of poverty indicate that the main determinants of poverty are educational attainment, number of household members, physical assets (land and house ownership), existence of migrant workers (possible remittances), negative shocks of layoffs and/or health problems, development of public services, and the availability of road infrastructure. A higher educational attainment increases the probability of never being poor in any of the five poverty metrics by almost 11 percentage points. This study also confirmed that households having less than society’s averages in terms of the physical asset of land and consumption of durable goods and fashion tended to subjectively asses themselves as poor. The study suggests that any poverty alleviation programs should consider relative impacts among beneficiaries and non-beneficiaries within each locality and across provinces.
Identification of surface markers for prospective isolation of human endometrial stromal colony-forming cells.

BACKGROUND Human endometrium is a highly regenerative tissue. We hypothesized that the source of endometrial stromal and vascular regeneration is a resident stromal stem/progenitor cell population. Putative human endometrial stromal stem/progenitor cells have been identified using clonal assays, a retrospective functional stem cell assay. Therefore, the aim of this study was to screen potential stem cell markers for the prospective isolation of human endometrial stromal stem/progenitor cells and to determine their capacity to identify colony-forming stromal cells. METHODS Single-cell suspensions of human endometrial stromal cells were sorted using fluorescence-activated cell sorting into positive and negative populations based on STRO-1, CD133, CD90 or CD146 expression for clonal assays. All markers were immunolocalized in human endometrium. RESULTS Small populations (2-9%) of human endometrial stromal cells expressed each of the markers. Only CD146(+) cells were enriched for colony-forming cells, and CD90(hi) cells showed a trend for greater enrichment compared with CD90(lo) cells. STRO-1 and CD146 were localized to perivascular cells of the endometrium. CD90 was strongly expressed by functionalis stroma and perivascular cells, but only weakly expressed in the basalis stroma. CD133 was expressed by epithelial cells of the endometrium, rather than by stroma or perivascular cells. CONCLUSIONS This study identified CD146 as a marker of colony-forming human endometrial stromal cells supporting the concept that human endometrium contains a population of candidate stromal stem/progenitor cells.
