Revisiting differential grading standards anno 2014: an exploration in Dutch higher education

The role that teachers have in assessing student coursework is crucial. Their ‘determination’ that a particular piece of student’s work is ‘acceptable’ has many serious consequences. With a lack of debate surrounding assessment, practices may become mired in conventions and disconnected from issues such as knowledge, power and social organisation. They may also become divergent between faculties, with majors with academically stronger students grading more stringently and those with academically weaker students grading less stringently. In order to test for potential differential grading standards due to adaption-level, this study examines the relationship of pre-entry secondary school grades (English, Dutch and Mathematics) to first-year average grades in 11 faculties (n = 3080). The results presented demonstrate the presence of differential grading standards among the different faculties within this population.
Security-Focused Survey on Group Key Exchange Protocols

In this paper we overview a large number of currently known group key exchange protocols while focusing on the protocols designed for more than three participants (for an overview of twoand three-party key exchange protocols we refer to [BM03, DB05c]). For each mentioned protocol we briefly describe the current state of security based on the original analysis as well as later results appeared in the literature. We distinguish between (i) protocols with heuristic security arguments based on informally defined security requirements and (ii) protocols that have been proven secure in one of the existing security models for group key exchange. Note, this paper continues the work started in [Man06] which provides an analytical survey on security requirements and currently known models for group key exchange. We emphasize that the following survey focuses on the security aspects of the protocols and does not aim to provide any efficiency comparison. The reader interested in this kind of surveys we refer to [RH03, AKNRT04].
Four Fallacies and an Oversight: Searching for Martian Life

Abstract While it is anticipated that future human missions to Mars will increase the amount of biological and organic contamination that might be distributed on that planet, robotic missions continue to grow in capability and complexity, requiring precautions to be taken now to protect Mars, and particularly areas of Mars that might be Special Regions. Such precautionary cleanliness requirements for spacecraft have evolved over the course of the space age, as we have learned more about planetary environments, and are the subject of regular deliberations and decisions sponsored by the Committee on Space Research (COSPAR). COSPAR's planetary protection policy is maintained as an international consensus standard for spacecraft cleanliness that is recognized by the United Nations Committee on the Peaceful Uses of Outer Space. In response to the paper presented in this issue by Fairén et al. (2017), we examine both their concept of evidence for possible life on Mars and their logic in recommending that spacecraft cleanliness requirements be relaxed to access Special Regions “before it is too late. ” We find that there are shortcomings in their plans to look for evidence of life on Mars, that they do not support their contention that appropriate levels of spacecraft cleanliness are unaffordable, that there are major risks in assuming martian life could be identified by nucleic acid sequence comparison (especially if those sequences are obtained from a Special Region contaminated with Earth life), and that the authors do not justify their contention that exploration with dirty robots, now, is preferable to the possibility that later contamination will be spread by human exploration. We also note that the potential effects of contaminating resources and environments essential to future human occupants of Mars are both significant and not addressed by Fairén et al. (2017).

Poly-victimization and executive functions in junior college students.

This study sought to characterize executive dysfunctions in poly-victimized students without posttraumatic stress disorder (PTSD) symptoms and the relationship between neuropsychological and behavioral rating measures of executive functions (EFs). Based on self-report data of exposure to victimization and PTSD symptoms, 259 junior college students aged 18-21 years were classified into four groups: poly-victimization with PTSD symptoms (PVP), poly-victimization without PTSD symptoms (PVnP), non-poly-victimization (nPV), and non-victimization (nV). Respondents also completed the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A). Of the 259 participants, 131 were administered a battery of neuropsychological tests from the Cambridge Neuropsychological Testing Automated Battery (CANTAB). The PVP group and the PVnP group performed worse than the nV group on most BRIEF-A scales. When compared with the nPV group, the PVP group demonstrated poorer performance on the scales of Inhibit, Shift, Emotional Control, Initiate, and Working Memory, while the PVnP group performed more poorly on the Working Memory scale and the Task Monitor scale. For all BRIEF-A scales, no significant differences were detected between the PVP group and the PVnP group. This study showed no between-group differences for most of the neuropsychological tests except for the Stop Signal Task (SST), and no correlations between these two measures of EFs. Overall, we found evidence of an association between deficits in EFs and poly-victimization. Although our study raises questions about the relationship between these two measures of EFs, it suggests that the use of the BRIEF-A in conjunction with the CANTAB provides a more complete assessment of the executive dysfunctions.
CEO Personality and Firm Policies

Based on two samples of high quality personality data for chief executive officers (CEOs), we use linguistic features extracted from conferences calls and statistical learning techniques to develop a measure of CEO personality in terms of the Big Five traits: agreeableness, conscientiousness, extraversion, neuroticism, and openness to experience. These personality measures have strong out-of-sample predictive performance and are stable over time. Our measures of the Big Five personality traits are associated with financing choices, investment choices and firm operating performance.
Modeling word burstiness using the Dirichlet distribution

Multinomial distributions are often used to model text documents. However, they do not capture well the phenomenon that words in a document tend to appear in bursts: if a word appears once, it is more likely to appear again. In this paper, we propose the Dirichlet compound multinomial model (DCM) as an alternative to the multinomial. The DCM model has one additional degree of freedom, which allows it to capture burstiness. We show experimentally that the DCM is substantially better than the multinomial at modeling text data, measured by perplexity. We also show using three standard document collections that the DCM leads to better classification than the multinomial model. DCM performance is comparable to that obtained with multiple heuristic changes to the multinomial model.
Age differences in younger and older adults' experience of interpersonal problems

Age Differences in Younger and Older Adults’ Experience of Interpersonal Problems Leo Schlosnagle Differences between younger (N=78) and older (N=78) adults’ frequency of experience of interpersonal problems were examined. Previous research has shown agerelated declines in contact frequency and negative interactions (Akiyama, et al., 2003; Carstensen, 1992). Aging has also been associated with concurrent increases in emotional closeness and relationship satisfaction with social partners (Birditt, et al., 2005; Lang & Carstensen, 2002), and social self-efficacy and problem-solving effectiveness (Artistico, Cervone, and Pezzuti, 2003; Blanchard-Fields, Mienaltowski, & Seay, 2007; Lachman, 1986). In the current study, older adults reported experiencing interpersonal problems significantly less often than younger adults. Older adults also reported less contact frequency with social partners, more self-efficacy, more positive relationship quality, and a lower degree of negative relationship quality than younger adults. Contact frequency and negative relationship quality both predicted frequency of experience of interpersonal problems. Among the contact frequency, self-efficacy, positive and negative relationship quality variables, none mediated an observed inverse relation between age and interpersonal problem frequency. Limitations and implications of the current study, as well as directions of future research are discussed.
Autoimmune metaplastic atrophic gastritis in chinese: a study of 320 patients at a large tertiary medical center

Abstract Objectives: Autoimmune metaplastic atrophic gastritis (AMAG) is an uncommon disease worldwide and may predispose to gastric carcinoid tumors or adenocarcinomas. The aims of this study were to outline the clinical characteristics of Chinese AMAG patients, including demographic pattern, hematologic features, and gastroscopic and histopathologic findings. Patients and methods: A total of 320 Chinese patients with AMAG, from January 2007 to December 2014, were reviewed in a regional hospital of China. Results: Of the 320 AMAG patients, the mean age was 60.6 ± 12.3 years [range 26–86; 206 (64.4%) women]. The coarse annual detection rate was 0.9%. Anemia was present in only 19.3% patients (53/275) and 3.5% (11/315) AMAG patients also had primary biliary cirrhosis. One hundred and thirty-six had endoscopically identifiable lesions. These lesions consisted of 130 polypoid lesions (63 hyperplastic polyps, 2 oxyntic mucosa pseudopolyps, 2 intestinal-type gastric adenomas, 2 fundic gland polyps, 5 concurrent polyps, 14 well-differentiated neuroendocrine neoplasms, 7 submucosal tumors and 35 chronic gastritis), 6 adenocarcinomas. The detection rate of atrophy and intestinal metaplasia in antral mucosa were 47.2 and 37.5%, respectively. Conclusions: AMAG is more frequent than expected in China and display a female predominance, accompanied with other autoimmune disorders. AMAG should be paid more attention by clinicians through a multidisciplinary team approach.
Degrees of Freedom in Planning, Running, Analyzing, and Reporting Psychological Studies: A Checklist to Avoid p-Hacking

The designing, collecting, analyzing, and reporting of psychological studies entail many choices that are often arbitrary. The opportunistic use of these so-called researcher degrees of freedom aimed at obtaining statistically significant results is problematic because it enhances the chances of false positive results and may inflate effect size estimates. In this review article, we present an extensive list of 34 degrees of freedom that researchers have in formulating hypotheses, and in designing, running, analyzing, and reporting of psychological research. The list can be used in research methods education, and as a checklist to assess the quality of preregistrations and to determine the potential for bias due to (arbitrary) choices in unregistered studies.
Systemic alendronate treatment improves fixation of press‐fit implants: A canine study using nonloaded implants

Bone resorption associated with local trauma occurring during insertion of joint prostheses is recognized as an early event. Being an osteoclastic inhibitor, alendronate is a potential candidate means to decrease early periprosthetic bone resorption and thereby improve implant fixation. We investigated the influence of oral alendronate treatment on early implant fixation in two implant interface settings representing sites of an implant that are in contact with surrounding bone, and other sites without intimate bone contact. One plasma‐sprayed cylindrical titanium implant (6 mm diameter) was inserted into each proximal tibia of 16 dogs. On one side the implant was inserted press‐fit whereas on the contralateral side, the implants were surrounded by a 2 mm concentric gap. Oral alendronate (0.5 mg/kg/day) was given 2 weeks following surgery to eight dogs. The dogs were euthanized after 10 weeks of alendronate treatment. Bone ongrowth (bone in contact with implant surface) was estimated using the linear intercept technique and shear strength was calculated as the slope on a load‐displacement curve. For the press fit implants, alendronate treatment significantly increased bone ongrowth from 24% to 29% and significantly increased ultimate shear strength from 1.26 to 3.72 MPa. Also, the fraction of periprosthetic bone significantly increased from 10% to 18%. For implants surrounded by a gap, alendronate neither stimulated nor impaired implant fixation, bone ingrowth, or new bone formation in the gaps. Because early implant stability is an important predictor of longevity, systemic alendronate treatment could be an important clinical tool to positively influence the early stages of implant incorporation. © 2006 Orthopaedic Research Society.

Decoupling of the brain's default mode network during deep sleep

The recent discovery of a circuit of brain regions that is highly active in the absence of overt behavior has led to a quest for revealing the possible function of this so-called default-mode network (DMN). A very recent study, finding similarities in awake humans and anesthetized primates, has suggested that DMN activity might not simply reflect ongoing conscious mentation but rather a more general form of network dynamics typical of complex systems. Here, by performing functional MRI in humans, it is shown that a natural, sleep-induced reduction of consciousness is reflected in altered correlation between DMN network components, most notably a reduced involvement of frontal cortex. This suggests that DMN may play an important role in the sustenance of conscious awareness.
Resuscitation of severe uncontrolled hemorrhage: 7.5% sodium chloride/6% dextran 70 vs 0.9% sodium chloride.

OBJECTIVES Resuscitation studies of hypertonic saline using controlled and uncontrolled hemorrhage models yield conflicting results with regard to efficacy. These disparate results reflect the use of models and resuscitation regimens that are not comparable between studies. This study evaluated the effects of comparable and clinically relevant resuscitation regimens of 7.5% sodium chloride/6% dextran 70 (HSD) and 0.9% sodium chloride (NS) in a near-fatal uncontrolled hemorrhage model. METHODS Thirty-six swine (14.2 to 21.4 kg) with 4-mm aortic tears were bled to a pulse pressure of 5 mm Hg (40-45 mL/kg). The animals were resuscitated with either NS or HSD administered in volumes that provided equivalent sodium loads at similar rates. Group II (n = 12) was resuscitated with 80 mL/kg of NS at a rate of 4 mL/kg/min. Group III (n = 12) received 9.6 mL/kg of HSD at a rate of 0.48 mL/kg/min. In both groups, crystalloid resuscitation was followed by shed blood infusion (30 mL/kg) at a rate of 2 mL/kg/min. Group I (controls; n = 12) were not resuscitated. RESULTS One-hour mortality was significantly greater in group I (92%) as compared with group II (33%) and group III (33%) (Fisher's exact test; p = 0.004). Intraperitoneal hemorrhage was significantly greater in group II (34 +/- 20 mL/kg) and group III (31 +/- 13 mL/ kg) as compared with group I (5 +/- 2 mL/kg) (ANOVA; p < 0.05). There was no significant difference in hemodynamic parameters between groups II and III. CONCLUSION In this model of severe uncontrolled hemorrhage, resuscitation with HSD or NS, administered in volumes that provided equivalent sodium loads at similar rates, had similar effects on mortality, hemodynamic parameters, and hemorrhage from the injury site.
Pregnancy outcome after gestational exposure to mebendazole: a prospective controlled cohort study.

OBJECTIVE Mebendazole is an anthelmintic that is commonly needed in women of reproductive age. Its use in pregnancy is a reason for concern for women and their health care providers. The purpose of this study was to examine the fetal safety of mebendazole. STUDY DESIGN The Israeli Teratogen Information Service prospectively collected and followed 192 pregnancies exposed to mebendazole in pregnancy, 71.5% of whom had first-trimester exposure. Pregnancy outcome was compared with that of a matched control group, who were counseled for nonteratogenic exposure. RESULTS There was no increase in the rate of major malformations between the groups (5/150 pregnancies [3.3%; mebendazole] vs 3/175 pregnancies [1.7%; nonteratogenic control subjects]; P =.478). There was a higher rate of elective terminations of pregnancy in the exposed group compared with the control group (22/192 pregnancies [11.5%; mebendazole] vs 3/192 pregnancies [1.6% [nonteratogenic control subjects]; P =.000). CONCLUSION This study suggests that mebendazole does not represent a major teratogenic risk in humans when it is used in the doses that are used commonly for pinworm (Enterobius vermicularis) infestation.
Reconceptualizing Innovation Compatibility as Organizational Alignment in Secondary IT Adoption Contexts: An Investigation of Software Reuse Infusion

This paper reconceptualizes the compatibility construct that has generated mixed results in the information systems (IS) literature and develops an organizational alignment (OA) framework for secondary IT adoption contexts, grounded in Leavitt's organizational change model and its extensions and applications in the IS area. Rooted in structuration and sensemaking theories, the paper conceptualizes OA as a representation of institutional structures of signification, domination, and legitimation, and proposes that perceived OA between an IT innovation and its complementary organizational components will impact secondary adoption behaviors of organizational members with respect to that innovation. This proposition is empirically evaluated through a field study of software reuse at a large U.S. bank. Survey data collected from IS professionals are analyzed using partial least squares (PLS). A model comparison approach is utilized to compare the influence of the compatibility and OA constructs on individual-level infusion behavior of IS professionals. Results provide good support for the research model. As hypothesized, the OA construct is found to be a significant predictor of infusion behavior. However, compatibility is found not to have a significant relationship with infusion behavior, adding to the mixed findings about this construct in the literature. Results of the study and its limitations, generalizability, contributions, and implications are discussed.
What it means to care: A meaning-focused expressive writing intervention for family caregivers

Title of Thesis: WHAT IT MEANS TO CARE: A MEANING-FOCUSED EXPRESSIVE WRITING INTERVENTION FOR FAMILY CAREGIVERS Amy Carr Fuhrmann, Master of Arts, 2015 Thesis directed by: Dr. Mary Ann Hoffman Department of Counseling, Higher Education, and Special Education Over 67 million adults in the U.S. provide informal or unpaid care to a loved one facing a health challenge, but caregivers often feel underprepared and isolated in this challenging role. There is a dearth of interventions to improve quality of life for caregivers. One hundred caregivers wrote three expressive writing essays about their experience in one of three randomly-assigned conditions: caregiver time-management, emotional expression, and meaning of caregiving. This study had two primary aims: 1) to investigate effects of writing among the three writing conditions on outcomes of depression, caregiver burden, intrusiveness, satisfaction with life, worldview violation, and meaning in life and 2) to assess whether meaning in life serves as a mediator for outcomes. Results indicated that some positive effects of expressive writing can be explained by the discovery of, but not simply the search for, meaning. Implications about understanding of the psychological experience of caregivers are discussed.
Loss of Visual Acuity is the Main Reason Why Reading Addition Increases After the Age of Sixty

Purpose. To determine why the reading addition increases after the age of 55 to 60 years when accommodation is zero. Methods. Distance and near visual acuities, arm length, habitual near working distance, reading addition, and pupil diameter were measured in 44 subjects aged >60 years (mean, 72.9 ± 5.7). Reading addition values were attained using three techniques: least-plus addition using both N-notation text and MN-READ text and the cross-cylinder technique. Results. The mean dioptric working distance was 2.75 ± 0.40 D. The reading addition found using N-notation text (+2.21 ± 0.38 D) was significantly lower than that measured using MN-READ text (+2.48 ± 0.49 D) or the cross-cylinder method (+2.53 ± 0.44 D). The reading addition was positively correlated with the dioptric working distance (r = 0.47, p < 0.01), and decreasing habitual working distance was associated with poorer visual acuity (r = −0.42, p < 0.01). Conclusions. Our results suggest that decreases in near visual acuity after 60 years of age lead to a reduction in habitual working distance, which increases text angular subtense. In turn, the reduced working distance requires a greater reading addition. Increases in depth of field associated with both suprathreshold text (N-notation) and lower visual acuity lead to reading additions being less than the dioptric working distance.
Structures and dynamics of hibernating ribosomes from Staphylococcus aureus mediated by intermolecular interactions of HPF

In bacteria, ribosomal hibernation shuts down translation as a response to stress, through reversible binding of stress‐induced proteins to ribosomes. This process typically involves the formation of 100S ribosome dimers. Here, we present the structures of hibernating ribosomes from human pathogen Staphylococcus aureus containing a long variant of the hibernation‐promoting factor (SaHPF) that we solved using cryo‐electron microscopy. Our reconstructions reveal that the N‐terminal domain (NTD) of SaHPF binds to the 30S subunit as observed for shorter variants of HPF in other species. The C‐terminal domain (CTD) of SaHPF protrudes out of each ribosome in order to mediate dimerization. Using NMR, we characterized the interactions at the CTD‐dimer interface. Secondary interactions are provided by helix 26 of the 16S ribosomal RNA. We also show that ribosomes in the 100S particle adopt both rotated and unrotated conformations. Overall, our work illustrates a specific mode of ribosome dimerization by long HPF, a finding that may help improve the selectivity of antimicrobials.
