Can computer personalities be human personalities?

The claim that computer personalities can be human personalities was tested by demonstrating that (1) computer personalities can be easily created using a minimal set of cues, and (2) that people will respond to these personalities in the same way they would respond to similar human personalities. The present study focused on the "similarity-attraction hypothesis," which predicts that people will prefer to interact with others who are similar in personality. In a 2 × 2, balanced, between-subjects experiment (n = 48), dominant and submissive subjects were randomly matched with a computer that was endowed with the properties associated with dominance or submissiveness. Subjects recognized the computer's personality type, distinct from friendliness and competence. In addition, subjects not only preferred the similar computer, but they were more satisfied with the interaction. The findings demonstrate that personality does not require richly defined agents, sophisticated pictorial representations, nautral language processing, or artificial intelligence. Rather, even the most superficial manipulations are sufficient to exhibit personality, with powerful effects.
Exosomes in Prostate Cancer: Putting Together the Pieces of a Puzzle

Exosomes have been shown to act as mediators for cell to cell communication and as a potential source of biomarkers for many diseases, including prostate cancer. Exosomes are nanosized vesicles secreted by cells and consist of proteins normally found in multivesicular bodies, RNA, DNA and lipids. As a potential source of biomarkers, exosomes have attracted considerable attention, as their protein content resembles that of their cells of origin, even though it is noted that the proteins, miRNAs and lipids found in the exosomes are not a reflective stoichiometric sampling of the contents from the parent cells. While the biogenesis of exosomes in dendritic cells and platelets has been extensively characterized, much less is known about the biogenesis of exosomes in cancer cells. An understanding of the processes involved in prostate cancer will help to further elucidate the role of exosomes and other extracellular vesicles in prostate cancer progression and metastasis. There are few methodologies available for general isolation of exosomes, however validation of those methodologies is necessary to study the role of exosomal-derived biomarkers in various diseases. In this review, we discuss “exosomes” as a member of the family of extracellular vesicles and their potential to provide candidate biomarkers for prostate cancer.
An assessment of strategies for improving quality of care in nursing homes.

PURPOSE Despite substantial regulatory oversight, quality of care in nursing homes remains problematic. This article assesses strategies for improving quality of care in these facilities. DESIGN AND METHODS This article reviews the research literature on eight strategies: strengthening the regulatory process, improving information systems for quality monitoring, strengthening the caregiving workforce, providing consumers with more information, strengthening consumer advocacy, increasing Medicare and Medicaid reimbursement, developing and implementing practice guidelines, and changing the culture of nursing facilities. RESULTS Although individual approaches vary, several themes emerge. First, several strategies require substantially more resources and will increase costs. Second, the research literature does not provide much guidance as to the effectiveness of these options. Third, several strategies assume a degree of data sophistication on the part of nursing homes that may not exist. Fourth, regulation is likely to continue to be the main strategy of quality assurance. Finally, the political saliency of nursing home quality issues is uneven. IMPLICATIONS Quality of care in nursing homes is a major issue for which there is no simple solution.
Maize Plant Resilience to N Stress and Post-silking N Capacity Changes over Time: A Review

We conducted a synthesis analysis on data from 86 published field experiments conducted from 1903 to 2014 to explore the specific consequences of post-silking N accumulation (PostN) in New Era vs. Old Era hybrids on grain yield (GY) and recovery from plant N stress at flowering (R1 stage). The Old Era encompassed studies using genotypes released before, and including, 1990 and the New Era included all studies using genotypes released from 1991 to 2014. Mean N fertilizer rates for experiments in the Old and New Era were similar (170 and 172 kg ha−1, respectively), but plant densities averaged 5.0 plants m−2 in the Old Era vs. 7.3 plants m−2 in the New Era studies. Whole-plant N stress at R1 for each hybrid, environment and management combination was ranked into one of three categories relative to the N Nutrition Index (NNI). The key findings from this analysis are: (i) New Era genotypes increased the proportion of the total plant N at maturity accumulated post-silking (%PostN) as N stress levels at R1 increased—demonstrating improved adaptability to low N environments, (ii) New Era hybrids maintained similar GY on a per plant basis under both low and high N stress at R1 despite being subject to much higher population stress, (iii) PostN is more strongly correlated to GY (both eras combined) when under severe R1 N stress than under less acute N stress at R1, (iv) the New Era accumulated more total N (an increase of 30 kg N ha−1) and higher %PostN (an increase from 30% in Old to 36% in New Era), and (v) the change in stover dry weight from silking to physiological maturity (ΔStover) has a positive, linear relationship with PostN in the Old Era but less so in the New Era. This increased understanding of how modern genotypes accumulate more N in the reproductive stage and have more PostN and GY resilience to mid-season N stress, even when grown at much higher plant densities, will assist trait selection and N management research directed to improving maize yields and N efficiencies simultaneously.
Role of Serum Zinc Level and P300 Event Related Potential in Detection of Minimal Hepatic Encephalopathy

Background: Minimal hepatic encephalopathy (MHE) is defined as hepatic encephalopathy (HE) without symptoms on clinical/neurological examination, but with deficits in some cognitive areas that can only be measured by neuropsychometric testing. Aim: Our aim was to study serum zinc levels in cirrhotic patients with and without MHE and correlate it with the results of neuropsychological tests and P300 event related potential. Patients and Methods: Fifty-five patients with liver cirrhosis were recruited for the present study. All patients were subjected to full history taking, clinical examination, abdominal ultrasonography, laboratory investigations including liver function tests and serum zinc, psychometric studies (line tracing test and serial dotting test) and P300 event related potential. According to the results of psychometric studies and P300 event related potential, the patients were divided into 3 groups in addition to the control group. Results: Among the 55 patients included in the study, 30 patients had no clinical evidence of HE and 25 patients had overt HE with different grades. In patients with no clinical evidence of HE, psychometric tests and P300 event related potential revealed that 13 patients had MHE, while 17 had no HE. There were significantly lower serum zinc levels in patients with MHE and in cirrhotic patients without HE compared with the healthy controls. Also, zinc levels were significantly lower in higher grades of hepatic encephalopathy. Serum zinc levels showed positive correlation with serum albumin levels and inverse correlation with serial dotting test and P300 latency. Conclusion: Reduced serum zinc level and prolonged P300 latency can serve as predictors of minimal hepatic encephalopathy in cirrhotic patients. Zinc deficiency is common in cirrhotic patients with MHE. These findings may have important prognostic and therapeutic implications in MHE and overt HE patients with zinc deficiency.
Best-Evidence Synthesis: An Alternative to Meta-Analytic and Traditional Reviews

This paper proposes an alternative to both meta-analytic and traditional reviews. The method, “best-evidence synthesis,” combines the quantification of effect sizes and systematic study selection procedures of quantitative syntheses with the attention to individual studies and methodological and substantive issues typical of the best narrative reviews. Best-evidence syntheses focus on the “best evidence” in a field, the studies highest in internal and external validity, using well-specified and defended a priori inclusion criteria, and use effect size data as an adjunct to a full discussion of the literature being reviewed.
Online Versus Traditional Master of Music in Music Education Degree Programs

The purpose of this study was to describe the reasons that two matriculated students had for enrollment into either an online or a traditional master of music in music education (MME) degree program. Research questions were the following: (a) What are the reasons each student gave for matriculating into either an online or a traditional MME program? (b) What are these students’ perceptions of both types of MME programs? How did those perceptions influence their decisions to matriculate into a respective program, if at all? Reasons for matriculating into a respective program included professional and financial obligations, creating relationships with faculty, perceived flexibility of the online program, and development of musician identity and musicianship. Implications include employing the hybrid course format to create a balance of both types of learning environments. Suggestions for future research include investigating the value that students find in an applied lesson and/or ensemble participation component of an MME program.
Information-Technology Investment Decisions: When Do Costs and Benefits in the Social Subsystem Matter?

The inclusion of social subsystem costs and benefits in information technology (IT) investment choices has been a difficult problem for IT decision-makers. Past research has shown that although some organizations adequately and consistently consider social subsystem issues when making IT investment decisions, many do not. This demonstrates a discrepancy between prescriptive theory and descriptive evidence. Our study addresses this theory-practice disconnection by investigating which firms, and under what conditions IT investments are likely to follow or violate prescriptions. Data collected from a national sample of 200 firms shed light on the firm and situational factors that affect the consideration of social subsystem issues during the IT investment decision process. The amount of social subsystem disruption associated with the IT in question, the strategic relevance of the IT to the organization, and the firm's continuous-learning culture each have direct or interactive influences on the decision process. Specifically, they impact the consideration of social subsystem costs and benefits for IT investments. Organizational size and industry are unrelated to this facet of decision-making. Overall, the empirical results help us better understand (1) what kinds of IT decisions cause stronger evaluation of social subsystem costs and benefits, (2) what types of firms give the greatest consideration to these issues, and (3) which intangible social subsystem costs or benefits are seen as the most important.
The applicability of course experience questionnaire for a Malaysian university context

Purpose – The purpose of this study is to examine the applicability of Course Experience Questionnaire (CEQ) in a Malaysian university context. Design/methodology/approach – The CEQ was translated into Malay language using rigorous cross-cultural adaptation procedures. The Malay version CEQ was administered to 190 undergraduate students in one Malaysian public university. Statistical analyses were used to examine the reliability and factor structures of the Malay version CEQ scales using IBM SPSS version 20.0. Findings – Findings raised serious questions about the reliability and construct validity of the CEQ for a Malaysian university sample. Findings revealed that only two out of five scales of CEQ showed satisfactory level of reliability. Six items failed to load on the intended scales. Research limitations/implications – The sample size is small with 190 university students and covered respondents from one local university, while the other 17 local universities were not included due to geographical di.
A cultural communities approach to understanding Head Start teachers’ beliefs about language use with dual language learners: Implications for practice

The school-readiness gap for Latino dual language learners in the United States has been well documented, despite a strong research base highlighting effective strategies and practices for supporting their academic success. However, current educational practices reflect the hegemonic discourse that, because the United States is an English-speaking country, English should be the language of instruction. Additionally, educational research during the past decade has been characterized by an emphasis on the use of rigorous experimental designs that are highly generalizable and fail to take into consideration the role of teacher beliefs on classroom practices. This study used a cultural communities lens to explore the beliefs about classroom language use of two Head Start teachers in order to gain insight into how teacher beliefs influence classroom practices, particularly the language of instruction. Analysis of teacher interviews and assessments of classroom language use indicated that teachers had very different beliefs about language use, despite their coming from very similar ethnic and linguistic backgrounds, and that these beliefs were translated into classroom practice. Teacher beliefs were grounded in teachers’ experiences as members of cultural communities, and the findings highlight the need to attend to within-group variability as well as classroom processes that influence teaching and learning.
The evolution and development of human cooperation

Humans have attained an unparalleled level of sophistication when engaging in collaborative and cooperative activities. Remarkably, the skills and motivation to engage in complex forms of collaboration and cooperation seem to emerge early on during infancy and childhood. In this paper, I extensively review the literature on the evolution and development of human cooperation, emphasizing important aspects of inter-cultural variation in collaborative and cooperative behaviour. This will not only allow us to confront the different evolutionary scenarios in which cooperation may have emerged, but will especially provide the reader with a first orientation in the abundant literature on human cooperation.
Association between single nucleotide polymorphisms in the antioxidant genes CAT , GR and SOD 1 , erythrocyte enzyme activities , dietary and life style factors and breast cancer risk in a Danish , prospective cohort study

Exposure to estrogens and alcohol consumption the two only well-established risk factors for breast cancer are capable of causing oxidative stress, which has been linked to progression of breast cancer. Here, five functional polymorphisms in the antioxidant genes SOD1, CAT and GSR were investigated in 703 breast cancer casecontrol pairs in the Danish, prospective “Diet, Cancer and Health” cohort together with gene-environment interactions between the polymorphisms, enzyme activities and intake of fruits and vegetables, alcohol and smoking in relation to breast cancer risk. Our results showed that genetically determined variations in the antioxidant enzyme activities of SOD1, CAT and GSR were not associated with risk of breast cancer per se. However, intake of alcohol, fruit and vegetables, and smoking status interacted with some of the polymorphisms in relation to breast cancer risk. Four polymorphisms were strongly associated with enzyme activity, but there was no interaction between any of the studied environmental factors and the polymorphisms in relation to enzyme activity. Additionally, single measurement of enzyme activity at entry to the cohort was not associated with risk of breast cancer. Our results therefore suggest that the antioxidant enzyme activities studied here are not major determinants of breast cancer risk.
Towards a Multicultural World: Identifying Work Systems, Practices and Employee Attitudes that Embrace Diversity

The research program described focuses on identifying the role of organisational culture, as reflected in workplace systems and practices, and employee and group attitudes in the outcomes of interactions among dissimilar parties. A systematic, theory-testing approach underlies the program, which aims to both develop and validate the diversity openness construct. The Perceived Dissimilarity-Openness Moderator Model developed from the research asserts that the affective, cognitive and behavioural consequences of diversity depend in part upon the perception of difference and subsequent quality and magnitude of the response to the perceived dissimilarity. When individuals or social systems (groups or organisations) are diversity-closed, outcomes are predicted to be less positive than when they are diversity-open.
An Assessment of Propensity Score Matching as a Non Experimental Impact Estimator : Evidence from a Mexican Poverty Program

Social experiments have become the benchmark method for estimating the program impacts of policy interventions, but are not always available. Non experimental evaluation methods provide an alternative to the experimental design, but their results depend on stronger non-testable assumptions and therefore are less clear and more controversial. We present evidence on the reliability of a non experimental method, propensity score matching, in the estimation of program impacts. We apply propensity score matching to estimate the bias associated with the treatment on the treated effect of a Mexican anti-poverty program on outcomes such as food expenditure and its composition, and children's schooling and employment. We compare the results of the experimental impact evaluation of the program with those using matched samples drawn from a nationally representative household survey. Our results show that simple cross-sectional matching does well in replicating the benchmark for outcomes that are measured using similar survey instruments. However, for outcomes that are measured using different survey instruments we find significant differences between the benchmark and the results based on matching. 1 Juan Jose Diaz is a graduate student in the Department of Economics, University of Maryland.

Being professional: accountability and authority in teachers’ responses to science curriculum reform

The science curriculum is a focus of repeated reform in many countries. However, the enactment of such reforms within schools rarely reflects the intended outcomes of curriculum designers. This review considers what we know about the experiences and reflections of teachers in the enactment of externally driven school science curriculum reform. ‘Externally driven’ signals a focus on studies of teachers who did not make a proactive choice to adopt a particular curriculum reform initiative. This is a very common experience for teachers in many school systems, and one likely to highlight issues of professionalism and authority that are central to the work of teachers. The review analyses 34 relevant studies. These include studies of teachers’ experiences of national curriculum reform, and also studies focusing on more regional or local curriculum reform activities. The studies examine individual teachers’ beliefs, practices and reflections associated with curriculum reform, the response of teacher communities to reform (e.g. within school departments), and teachers’ (and other stakeholders’) experiences across school systems. A wide range of factors influencing teachers’ responses are identified. These are characterised in terms of personal, internal and external contexts of teachers’ work. The review also highlights issues of authority, professionalism and the process of meaning-making in response to external curriculum reform. The discussion section identifies important areas for future research and gives recommendations for the design of curriculum policies that recognise and support the professionalism of science teachers.
Keratan sulfate glycosaminoglycan and the association with collagen fibrils in rudimentary lamellae in the developing avian cornea.

PURPOSE Keratan sulfate (KS), through its association with fibrillar collagen as KS-substituted proteoglycan (KS PG), is thought to be instrumental in the structural development of the corneal stroma. The authors used two different sulfate motif-specific antibodies to identify the sequence of appearance, and the association with collagen, of sulfated KS during avian corneal morphogenesis. METHODS Corneas from chicken embryos throughout the developmental period, from day 8 through day 18 of incubation, were examined by immunofluorescence and immunoelectron microscopy using monoclonal antibodies 5D4 and 1B4, which react with high- and low-sulfated epitopes on KS, respectively. RESULTS KS was identified as punctate labeling at incubation day 8, the earliest stage examined, suggesting a cell-associated distribution. By day 10, labeling was more homogeneous, indicating that KS sulfation motifs were present in the stromal extracellular matrix. At day 12 through day 14, immunopositive sites were concentrated primarily in the anterior stroma but became more uniform throughout the full stromal thickness by day 18. From day 10 on, electron microscopy revealed a high-sulfated KS epitope closely associated with bundles of regularly arranged collagen fibrils, initially near cell surfaces in rudimentary lamellae. Individual cells, associated with collagen bundles with different fibril orientations, imply the potential for simultaneous deposition of multiple lamellae. CONCLUSIONS During chick corneal morphogenesis, significant matrix deposition of high-sulfated KS epitope occurs by day 10, with accumulation subsequently proceeding in an anterior-to-posterior manner. High-sulfated KS likely serves to help define the regular spatial organization of collagen fibrils in bundles newly extruded into the extracellular milieu.
