An Exploration of Policies Governing Faculty-to-Student Consensual Sexual Relationships on University Campuses: Current Strategies and Future Directions

Consensual sexual relationships between students and faculty have traditionally been viewed as private matters and have been ignored by university administrators except in cases that resulted in sexual harassment claims. Due to increasing sexual harassment litigation and the liabilities associated with such relationships, universities have developed policies to limit relationships between faculty and students and to acknowledge the power differential inherent in such relationships. These policies, however, differ between universities, causing confusion among the university community as to what is considered acceptable and ethical behavior. Using a sample of 55 universities, this analysis attempted to determine (a) the level of acceptability of such relationships, (b) the language or absence thereof addressing power differentials, (c) liability issues associated with these relationships, (d) reporting requirements, and (e) whether clearly outlined sanctions exist when/if such relationships occur. Future directions for research and policy are also discussed.
Overexpression of B2M and loss of ALK7 expression are associated with invasion, metastasis, and poor-prognosis of the pancreatic ductal adenocarcinoma.

BACKGROUND Approximately 80% of patients with pancreatic ductal adenocarcinoma (PDAC) have metastatic disease with poor prognosis, but clinically available markers have not yet been identified. OBJECTIVE In this study, we investigated the expression of B2M and ALK7 in 106 PDACs compared to precursor lesions of the pancreas. METHODS Immunohistochemistry was used to detect B2M and ALK7 protein expression. RESULTS Positive B2M expression was significantly higher, while positive expression of ALK7 was significantly lower in PDAC than in precursor lesions (p < 0.01 or p < 0.001). Positive B2M expression was also significantly higher, while positive ALK7 expression was significantly lower in cases with well-differentiated adenocarcinoma, small tumor mass, no-metastasis of the lymph node, no-invasion of regional tissues, and TNM I or II stage disease than in cases having poorly-differentiated adenocarcinoma, large tumor mass, with metastasis and invasion, and TNM stage III or IV stage disease (p < 0.01). Univariate Kaplan-Meier analysis showed that B2M overexpression (p < 0.001), but lack of ALK7 expression (p < 0.001) was significantly associated with shorter overall survival. Cox multivariate analysis showed that differentiation, tumor mass, lymph node metastasis, invasion, TNM stage, and B2M levels negatively correlated with overall survival. In contrast, ALK7 level positively correlated with overall survival. Positive B2M and negative ALK7 expression are poor prognostic factors in PDAC patients. CONCLUSIONS B2M and ALK7 might be important biological markers involved in the carcinogenesis, metastasis, invasion, and prognosis of PDAC.
Resilience, Flexibility and Adaptive Management - - Antidotes for Spurious Certitude?

In many cases, a predicate of adaptive environmental assessment and management (AEAM) has been a search for flexibility in management institutions, or for resilience in the ecological system prior to structuring actions that are designed for learning. Many of the observed impediments to AEAM occur when there is little or no resilience in the ecological components (e.g., when there is fear of an ecosystem shift to an unwanted stability domain), or when there is a lack of flexibility in the extant power relationships among stakeholders. In these cases, a pragmatic solution is to seek to restore resilience or flexibility rather than to pursue a course of broad-scale, active adaptive management. Restoration of resilience and flexibility may occur through novel assessments or small-scale experiments, or it may occur when an unforeseen policy crisis allows for reformation or restructuring of power relationships among stakeholders.
Effectiveness of Personal Interaction in a Learner-Centered Paradigm Distance Education Class Based on Student Satisfaction

Abstract This study examined relationships between students’ perceptions of course-related interaction and their course satisfaction within the learner-centered paradigm in distance education. A Students’ Perceived Interaction Survey (SPIS) instrument was developed to examine nine separate hypotheses about the nature of course-related interaction. A volunteer sample of 855 students from the 949 students enrolled in Computer Science 103—Computer Literacy and Applications at Iowa State University in the fall of 2005 was used. This study employed a multiple linear regression. It concluded that student-instructor personal interaction, student-student personal interaction, and student-content interaction, along with students’ perceptions of WebCT features and gender were predictors of course satisfaction. In this study 94% of the participants indicated they were satisfied with the course. No significance was found in the relationships between student satisfaction and student-teaching assistant (TA) personal interaction, the student’s prior partial online distance education experience, the student’s prior entirely online distance education experience, and academic year.
The Extreme Right Filter Bubble

Due to its status as the most popular video sharing platform, YouTube plays an important role in the online strategy of extreme right groups, where it is often used to host associated content such as music and other propaganda. In this paper, we develop a categorization suitable for the analysis of extreme right channels found on YouTube. By combining this with an NMF-based topic modelling method, we categorize channels originating from links propagated by extreme right Twitter accounts. This method is also used to categorize related channels, which are determined using results returned by YouTube’s related video service. We identify the existence of a \lter bubble", whereby users who access an extreme right YouTube video are highly likely to be recommended further extreme right content.
“I’m Part of This Family”: How Five Care-Giving Partners of Gay Men Story Their Experiences

This study explores how five care-giving partners of gay men with chronic illness “story” their experiences, or how they construct their experiences in narrative form. Participants, all of whom were recruited with the help of local social service agencies, took part in two in-depth semi-structured interviews intended to invoke their stories as care-giving partners of gay men. Narrative analysis was used to conceptualize the respondents’ experiences. Several themes emerged in the study, many of which arguably related to participants’ real or perceived need to negotiate expressions of homophobia and heterosexism in the context of their care-giving narratives.
Physical Activity, Obesity, Weight Change, and Risk of Atrial Fibrillation: The Atherosclerosis Risk in Communities Study

Background—Physical activity (PA) has previously been suggested to attenuate the risk of atrial fibrillation (AF) conferred by excess body weight and weight gain. We prospectively examined the relationship between body size, weight change, and level of PA in a biracial cohort of middle-aged men and women. Methods and Results—Baseline characteristics on risk factor levels were obtained on 14 219 participants from the Atherosclerosis Risk in Communities Study. AF incidence was ascertained from 1987 to 2009. Adjusted Cox proportional hazards models were used to estimate the associations between body mass index, waist circumference, relative weight change, and PA level with incident AF. During follow-up, there were 1775 cases of incident AF. Body mass index and waist circumference were positively associated with AF as was weight loss/gain of >5% initial body weight. An ideal level of PA had a small protective effect on AF risk and partially attenuated the risk of AF associated with excess weight in men but not women: compared with men with a normal body mass index, the risk of AF in obese men with an ideal, intermediate, and poor level of PA at baseline was increased by 37%, 129%, and 156% (Pinteraction=0.04). During follow-up, PA did not modify the association between weight gain and risk of AF. Conclusions—Obesity and extreme weight change are risk factors for incident AF, whereas being physically active is associated with a small reduction in risk. In men only, being physically active offset some, but not all, of the risk incurred with excess body weight.
Emotion and attention interaction: a trade-off between stimuli relevance, motivation and individual differences

Mounting evidence suggests that the neural processing of emotional stimuli is prioritized. However, whether the processing of emotional stimuli is dependent on attention remains debatable. Several studies have investigated this issue by testing the capacity of emotional distracters to divert processing resources from an attentional main task. The attentional load theory postulates that the perceptual load of the main task determines the selective processing of the distracter. Although we agree with this theory, we also suggest that other factors could be important in determining the association between the load of the main task and distracter processing, namely, (1) the relevance of the to-be ignored stimuli and (2) the engagement in the main task due to motivation. We postulate that these factors function as opposite forces to influence distracter processing. In addition, we propose that this trade-off is modulated by individual differences. In summary, we suggest that the relationship between emotion and attention is flexible rather than rigid and depends on several factors. Considering this perspective may help us to understand the divergence in the results described by several studies in this field.
ABA-Based Programs for Children Diagnosed With Autism Spectrum Disorder: Parental and Professional Experiences at School and at Home

Having a child diagnosed with Autism Spectrum Disorder (ASD) poses a range of challenges to families, many of which can be addressed through appropriate intervention. A study of parental (n = 95) and professional (n = 67) experiences was carried out in relation to two settings: (a) schools that provided intensive interventions based on the science of Applied Behavior Analysis (ABA), and (b) non-intensive ABA-based home programs. Results show that parents whose children attend ABA-based schools were generally more satisfied with their child's educational provision, monitoring procedures, and level of staff training, than parents who were not offered ABA-based education in schools.
Preliminary experiments using subjective logic for the polyrepresentation of information needs

According to the principle of polyrepresentation, retrieval accuracy may improve through the combination of multiple and diverse information object representations about e.g. the context of the user, the information sought, or the retrieval system [9, 10]. Recently, the principle of polyrepresentation was mathematically expressed using subjective logic [12], where the potential suitability of each representation for improving retrieval performance was formalised through degrees of belief and uncertainty [15]. No experimental evidence or practical application has so far validated this model. We extend the work of Lioma et al. (2010) [15], by providing a practical application and analysis of the model. We show how to map the abstract notions of belief and uncertainty to real-life evidence drawn from a retrieval dataset. We also show how to estimate two different types of polyrepresentation assuming either (a) independence or (b) dependence between the information objects that are combined. We focus on the polyrepresentation of different types of context relating to user information needs (i.e. work task, user background knowledge, ideal answer) and show that the subjective logic model can predict their optimal combination prior and independently to the retrieval process.
Self-oscillating Water Chemiluminescence Modes and Reactive Oxygen Species Generation Induced by Laser Irradiation; Effect of the Exclusion Zone Created by Nafion

Samples of water inside and outside an exclusion zone (EZ), created by Nafion swollen in water, were irradiated at the wavelength l = 1264 nm, which stimulates the electronic transition of dissolved oxygen from the triplet state to the excited singlet state. This irradiation induces, after a long latent period, chemiluminescence self-oscillations in the visible and near UV spectral range, which last many hours. It occurs that this effect is EZ-specific: the chemiluminescence intensity is twice lower than that from the bulk water, while the latent period is longer for the EZ. Laser irradiation causes accumulation of H2O2, which is also EZ-specific: its concentration inside the EZ is less than that in the bulk water. These phenomena can be interpreted in terms of a model of decreasing O2 content in the EZ due to increased chemical activity of bisulfite anions (HSO3-), arisen as the result of dissociation of terminal sulfonate groups of the Nafion. The wavelet transform analysis of the chemiluminescence intensity from the EZ and the bulk water gives, that self-oscillations regimes occurring in the liquid after the latent period are the determinate processes. It occurred that the chemiluminescence dynamics in case of EZ is characterized by a single-frequency self-oscillating regime, whereas in case of the bulk water, the self-oscillation spectrum consists of three spectral bands.
Weighing and Body Monitoring Among College Women: The Scale Number as an Emotional Barometer

This study investigated weighing and body-monitoring behaviors, as well as psychological and behavioral reactions to weighing, among female college students. Weighing and body monitoring were engaged in by the majority of participants. Participants changed food intake and exercise based on weight. About 63% reported that the scale number impacts their mood, and 50% and 48% indicated that it impacts their sexual comfort and self-esteem, respectively. Most did not perceive self-weighing to be harmful. College counselors should be aware that weighing and body monitoring are normative, with negative psychological outcomes associated with weighing for a substantive percentage of college women.
Gender Differences in Reward Preference

Extensive research has explored apparent differences in task group members'preferences for reward allocation. Some seem to prefer distributions based on equity, others a distribution based on equality. At one time, the research strongly suggested that men tended to prefer equity and women tended to prefer equality. However, in recent years that result has only been inconsistently found Using the conceptual tools of Berger, Fisek, Norman, and Wagner's reward expectation theory, an account of differences in reward preferences based on status positions in the group is developed and tested experimentally. Basically, the reward expectation argument is that group members differentiated by status will prefer equity allocations and members equated (or never differentiated) by status will prefer equality allocations. The results strongly support the reward expectation interpretation.
Opacity: A Correctness Condition for Transactional Memory

Transactional memory is perceived as an appealing alternative to critical sections for general purpose concurrent programming. Despite the large amount of recent work on transactional memory implementations, however, its actual specification has never been precisely defined. This paper presents opacity, a new correctness criterion for transactional memory systems. Opacity extends the notion of strict serializability, itself a strong form of the classical serializability property, with the requirement that even non-committed transactions are prevented from accessing inconsistent state. Yet opacity does not preclude versioning, invisible reads and lazy updates, often used by modern TM implementations. In fact, most transactional memory systems we know of ensure opacity. We prove a tight bound on the inherent cost of implementing opacity. The bound highlights a trade-off that explains some of the differences between current transactional memory systems, and also draws a sharp complexity line between opacity on one hand, and the combination of strict serializability and strict recoverability on the other hand.
Anxiety in Children and Young Adolescents who Stutter

The present study was designed to investigate the question of whether children who stutter have raised levels of state and trait anxiety in comparison to children who do not stutter. If anxiety levels are raised, this would have implications for current theories of the cause of stuttering as well as for treatment in this age group. Ninety-six children aged 9–14 years who stuttered were compared with 104 children who did not stutter and who were similar in age and education levels. The experimental group were comprehensively diagnosed for stuttering and assessed for their severity by measuring stuttering frequency and speech rate in a five minute clinic conversation. Both groups completed the Spielberger STAIC anxiety questionnaire. Based on STAIC scores, those in the stuttering group were no more anxious than the controls. There were also no significant associations between severity of stuttering, age or sex, and levels of anxiety. Implications for the early management of stuttering are discussed.
How Big (Small?) are Fiscal Multipliers?

We contribute to the intense debate on the real effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a novel quarterly dataset of government expenditure in 44 countries, we find that (i) the output effect of an increase in government consumption is larger in industrial than in developing countries, (ii) the fisscal multiplier is relatively large in economies operating under predetermined exchange rate but zero in economies operating under flexible exchange rates; (iii) fiscal multipliers in open economies are lower than in closed economies and (iv) fiscal multipliers in high-debt countries are also zero.
Cultural values and attitudes towards guidance and counselling services in one secondary school in Malaysia: the role of a school cultural system

This narrative ethnographic study aims to explore students' attitudes towards guidance and counselling services in one secondary school in Malaysia. Semi-structured individual interviews, group interviews and observations were conducted with school students of different racial backgrounds. They were identified as referred clients, self-referred clients, and those not deemed to be involved in counselling. The data were analysed using the constant comparative analysis grounded theory approach. The findings indicate that there were different attitudes among the three groups of participants concerning counselling services. The study highlights the role of a school system in elucidating attitudes towards guidance and counselling services. It poses implications for understanding counselling services within the school system.
Do Depressive Symptoms Differ Between Medically Ill and Non-Medically Ill Patients Referred for Psychological Therapy? Comparing Negative Thoughts about the Self in Cancer and Non-Cancer Patients

Negative thoughts about the self are a core component of Beck's cognitive triad of depression, and are seen by some as the central cognitive symptom of the disorder. The role of negative thoughts about the self in secondary depression associated with medical illness is less clear: thoughts relating to hopelessness and helplessness rather than guilt, self blame and failure may be more prominent. This study tested the hypothesis that the cognitive symptoms of depression in cancer patients would be less negatively self-referent than a psychiatric control group. Forty patients with cancer referred to a psychological medicine department were matched for age, sex and BDI score with 40 patients referred to a psychological therapies department for CBT. The cognitive-affective section of the BDI (items 1–14) was divided into a negative self-referent cognitions subscale (items 3, 5, 7, 8) and a mood-motivation subscale. These two subscales were then compared with the somatic-performance subscale (items 15–21). As a percentage of the total matched BDI score, the cancer patients had more somatic symptoms (42.7 v 34.8%), equivalent mood/motivation symptoms (44.5 v 45.6%) and less negative self-referent symptoms (12.8 v 19.5%). This difference may apply more to mild symptoms than moderate-severe symptoms. Some preliminary support for the hypothesis is therefore available.
Lexical retrieval in discourse: An early indicator of Alzheimer’s dementia

Abstract We examined the progression of lexical-retrieval deficits in individuals with neuropathologically determined Alzheimer’s disease (AD; n = 23) and a comparison group without criteria for AD (n = 24) to determine whether linguistic changes were a significant marker of the disease. Our participants underwent multiple administrations of a neuropsychological battery, with initial administration occurring on average 16 years prior to death. The battery included the Boston Naming Test (BNT), a letter fluency task (FAS) and written description of the Cookie Theft Picture (CTP). Repeated measures analysis revealed that the AD-group showed progressively greater decline in FAS and CTP lexical performance than the comparison group. Cross-sectional time-specific group comparisons indicated that the CTP differentiated performance between the two groups at 7–9 years prior to death and FAS and BNT only at 2–4 years. These results suggest that lexical-retrieval deficits in written discourse serve as an early indicator of AD.
Characteristics of Infant Homicides: Findings From a U.S. Multisite Reporting System

OBJECTIVE: The purpose of this study was to describe homicides of infants (children <2 years of age) in the U.S. METHODS: Cases were derived from the National Violent Injury Statistics System; 71 incidents involving 72 infant homicides were in the data set. Type 1 involved beating/shaking injuries inflicted by a caretaker; type 2 involved all other homicides (including neonaticide, intimate partner problem-related homicide, crime-related death, and other types). RESULTS: Seventy-five percent of the incidents were type 1 incidents, perpetrated mainly by men (83%; typically the infant's father or the boyfriend of the infant's mother). In 85% of the type 1 incidents, the infant was transported to the hospital, usually at the initiative of the perpetrator or another household member. In almost one half of the type 1 incidents, a false story was offered initially to explain the injuries. In contrast, the type 2 incidents (16 cases) were perpetrated mainly by women (11 of 16 cases) and involved methods such as poisoning, drowning, sharp instruments, or withdrawal of food and water; most infants were not taken to the hospital. Although 93% of incidents were perpetrated by caretakers, the large differences between the 2 incident types suggest different avenues for prevention. CONCLUSIONS: The circumstances involved in the type 1 homicides (beatings by caretakers) suggested that those attacks occurred impulsively, death was unintended, and emergency care was summoned, often with a false story. Previous abuse was suspected in more than one half of those incidents.
