Having as a starting point the dispute between the Empathy – Altruism Hypothesis and the Aversive Arousal Reduction Hypothesis, the present research focus on the study of the motives underlying prosocial behavior. Thus, an experimental process was designed in which male and female adults took part (N = 128). Participants first completed the Prosocial Tendencies Measure (PTM, Carlo & Randal, 2002) and the Toronto Empathy Questionnaire (TEQ, Spreng et al., 2009). Then, based on their answers, participants were assigned to eight groups and exposed to different experimental conditions (2 known – unknown x 2 in need of help – without need of help x 2 compel to receive help – absence of compel to receive help). Findings indicate that the level of empathy experiencing by the “benefactor” plays an important role in the performance of prosocial behavior. Nevertheless, the variable of familiarity with the person in need was found to be crucial in the performance of prosocial behavior as well as the need for help. Furthermore, findings suggest that the performance of prosocial behavior is a consequence of psychological pressure to the “benefactor” who, in turn, seems to use the performance of such a behavior as a means of psychological escape from a condition in which the request of help is salient.

ABSTRACT Oestriol (oestra-1,3,5(10)-triene-3,16α,17β-triol) is a weakly oestrogenic substance which, however, in contrast to what was formerly believed, is of physiological significance. Its effect is localized largely to the uterine cervix and vagina. Clinical experience argues both for and against an effect on the pituitary gland. This investigation is concerned with the morphological changes in the pituitary gland and adrenal cortex of gonadectomized male and female rats after the injection of oestriol. It was found that oestriol has the same type of action on these glands as other oestrogens, but under the experimental conditions used, this effect proved much weaker than that produced by oestradiol (oestra-1,3,5(10)-triene-3,17β-diol).

Taking as a starting point the frequent characterisation of self-harm as “an adolescent thing for girls,” this paper offers a sociologically informed, qualitative exploration of self-harm as a gendered practice. We move beyond statistical constructions of this “reality,” and critically examine how this characterisation comes to be, and some of its effects. Our data are drawn from a pilot study that developed a collaborative arts-based inquiry into meanings of self-harm. The authors worked with two groups: one of practitioners and another of people who had self-harmed, meeting over six sessions to discuss and make art in response to a range of themes relating to the interpretation and explanation of self-harm. Through data generation and analysis, we collaboratively seek to make sense of the gendering of self-harm, focusing on a series of dualistic Cartesian “cuts” between male and female, violence and vulnerability, and inside and outside. In conclusion, we call for more multi- and interdisciplinary explorations of self-harm, and greater use of diverse, arts-based, and qualitative methodologies, in order to further expand and nuance understandings and ethical engagements with self-harm, and those who are affected by it.

The number of family caregivers to individuals with dementia is increasing. Family physicians are often the first point of access to the health care system for individuals with dementia and their caregivers. Caregivers are at an increased risk of developing negative physical, cognitive and affective health problems themselves. Caregivers also describe having unmet needs to help them sustain care in the community. Family physicians are in a unique position to help support caregivers and individuals with dementia, but often struggle with keeping up with best practice dementia service knowledge. The Dementia Wellness Questionnaire was designed to serve as a starting point for discussions between caregivers and family physicians by empowering caregivers to communicate their needs and concerns and to enhance family physicians’ access to specific dementia support information. The DWQ aims to alert physicians of caregiver and patient needs. This pilot study aimed to explore the experiences of physicians and caregivers of people using the Questionnaire in two family medicine clinics in Ontario, Canada. Interviews with physicians and caregivers collected data on their experiences using the DWQ following a 10-month data gathering period. Data was analyzed using content analysis. Results indicated that family physicians may have an improved efficacy in managing dementia by having dementia care case specific guidelines integrated within electronic medical records. By having time-efficient access to tailored supports, family physicians can better address the needs of the caregiver–patient dyad and help support family caregivers in their caregiving role. Caregivers expressed that the Questionnaire helped them remember concerns to bring up with physicians, in order to receive help in a more efficient manner.

The concept of bracketed morality has received empirical support in several sport studies (e.g., Bredemeier & Shields, 1986a, 1986b). However, these studies have focused on moral reasoning. In this research, we examined bracketed morality with respect to moral behavior in sport and university contexts, in two studies. Male and female participants (Study 1: N = 331; Study 2: N = 372) completed questionnaires assessing prosocial and antisocial behavior toward teammates and opponents in sport and toward other students at university. Study 2 participants also completed measures of moral disengagement and goal orientation in both contexts. In most cases, behavior in sport was highly correlated with behavior at university. In addition, participants reported higher prosocial behavior toward teammates and higher antisocial behavior toward opponents in sport than toward other students at university. The effects of context on antisocial behavior were partially mediated by moral disengagement and ego orientation. Our findings extend the bracketed morality concept to prosocial and antisocial behavior.

My object in this paper is to give a brief note of a trial which has recently been made in the Fife Asylum, in the way of introducing female nursing in the male sick-room. Nursing is peculiarly woman's province; and it has, I believe, often been felt that it would be a great advantage if female care could be more freely utilised in the management of male insane patients, or at least of those of them who are suffering from special bodily disease in addition to the mental symptoms. The main objections to the step have hitherto been: (1) that some of the habits and peculiarities of the male insane may make it unfit or undesirable to have them under female care; and (2) that in many asylums the structural arrangement makes it difficult or impossible to bring the male sick-room under systematic supervision by the female staff. Lately it was necessary to build a large addition to the Fife Asylum; and advantage was taken of this opportunity to get rid of the second objection mentioned. The new building is a hospital block, and is intended to receive recent admissions, cases requiring special observation on account of their mental state, and cases of bodily illness. Each side (male and female) is divided into three sections: 1st, sickroom proper (for cases of bodily illness); 2nd, special observation ward (intended for new cases, and cases needing continuous supervision on account of suicidal or other dangerous tendency); and 3rd, general observation ward. There are the usual dining-hall, kitchen, and administrative rooms in the centre of the building. The male and female sick-rooms are placed next to the administrative portion, one on each side; and as the doors here are unlocked during the day, with free communication by the corridor, the male sick-room is easily reached from the female side, and is administered by the matron, the head nurse (who has charge of both sick-rooms), and two junior nurses. Each sick-room communicates with a special observation dormitory, beyond which again is the special observation day-room. This dormitory is empty during the day, but receives at night the cases which require continuous supervision on account of suicidal tendency, and which come to it direct from the special observation day-room. On the male side the door between the sick-room and the observation dormitory is kept locked during the day; and there is thus no direct communication between the sick-room and those parts of the male side which are under the charge of attendants, except by the general corridor. When the Medical Officer makes the evening visit, this door is unlocked, and the sick-room and observation dormitory are thrown into one and come under the charge of a male attendant, who is on duty during the whole night, while the nurses return to the female side of the building. This plan was followed because our numbers are too small to require separate attendance in the two rooms; and in this way the sick-room is under female care during the day, but is supervised at night by the male staff.∗

Several clinically used anticancer drugs are well-known as far as their pharmacologic properties are concerned, but scarcely ever the interest towards their physico-chemical characteristics in solution led to practical acknowledgement in their management. Thanks to the Units for Centralized Anticancer Drug Handling, the importance to evaluate the concentration of saturation (physical stability) or the possible transformations undergone by a drug in solution (chemical stability) has become the starting point for avoiding useless wasting drugs and economic resources. By HPLC experiments we have demonstrated that the solutions of two drugs, docetaxel and irinotecan, are particularly stable at different concentrations and times of analyses in our experimental conditions. The best mobile phase for docetaxel was water/methanol/acetonitrile in 42/32/26 volumetric ratio: for halving concentrations (0.72-0.36-0.18-0.09 mg/mL) in NaCl 0.9%, the highest value gave a six-day and the three lower concentrations a fourteen-day stability, when storage occurred at room temperature and light protected. Elution of irinotecan was possible through an analysis in mobile phase gradient: at t0 a 20% ammonium acetate 10 mM and 80% methanol mixture, and after 5 min, a 80% ammonium acetate 10 mM and 20% methanol mixture. The physico-chemical stability was showed for five days, for any concentration of analysis when storage occurred at 2-8°C and light protected.

Abstract Proppant placement concentration, particle size and creep time are important factors that affect the embedment of proppant into coal. Based on multistage creep, an orthogonal test is conducted, and an optimal proppant scheme for different closure stresses obtained. The results show that with increased proppant placement concentration, the number of coal fractures increases and the elastic modulus of the fracture area decreases. As the proppant particle size decreases, the plasticity of fracture-proppant assemblies increases gradually. The yield limit is highest when the particle size is 20/40 mesh. During the proppant embedding process, localization or uneven distribution of proppant results in tensile stress parallel to the fracture surface, which induces tensile fracture in the coal. In the fracture-proppant assembly areas, proppant fractures are severe and yield lines appear. As proppant concentration increases, more energy is accumulated during the proppant compaction stage, resulting in energy release producing craters and crevasses. The energy released also causes increased stress in the proppant-coal contact area and fracturing to the coal mass. The longer the creep time, the weaker the impact and the smaller is fluctuation. Moreover, we find that the orthogonal test can effectively analyze the importance of each parameter. Proppant placement concentration was found to have the highest influence on the process of proppant embedding into coal, followed by particle size and then time. Under experimental conditions, the lowest proppant-embedded value in coal samples was observed with proppant placement concentration of 2 kg m−2 and particle size of 20/40 mesh.

The accurate quantification of changes in the abundance of proteins is one of the main applications of proteomics. The maintenance of accuracy can be affected by bias and error that can occur at many points in the experimental process, and normalization strategies are crucial to attempt to overcome this bias and return the sample to its regular biological condition, or normal state. Much work has been published on performing normalization on data post-acquisition with many algorithms and statistical processes available. However, there are many other sources of bias that can occur during experimental design and sample handling that are currently unaddressed. This article aims to cast light on the potential sources of bias and where normalization could be applied to return the sample to its normal state. Throughout we suggest solutions where possible but, in some cases, solutions are not available. Thus, we see this article as a starting point for discussion of the definition of and the issues surrounding the concept of normalization as it applies to the proteomic analysis of biological samples. Specifically, we discuss a wide range of different normalization techniques that can occur at each stage of the sample preparation and analysis process.

There are situations in which intraradicular retainers have to be removed and replaced. The objective of this research was to evaluate the apical seal after the removal of a custom cast post and core with a carbide bur or with an ultrasound apparatus. Twenty five roots of extracted human incisors were used. They were endodontically treated and prepared to receive the posts. The posts and cores were cast with 2 types of dental alloys, CuAlZn and PdAg, and were cemented with zinc phosphate cement. After 24 hours, they were removed using the two above mentioned techniques. Then, the roots had their external surface made impermeable by two layers of cyanoacrylate adhesive, leaving only the cervical area for dye penetration. The teeth were immersed in rhodamine for 24 hours. They were then cut and observed under an optical microscope and analyzed with appropriate software (Imagelab). The results were submitted to ANOVA, and they evidenced that, regarding the alloy factor, PdAg posts presented a larger mean infiltration value (2.23 ± 0.48 mm) as compared to the posts made of CuAlZn (1.39 ± 0.48 mm) (p = 0.025). Regarding the technique factor, there was no significant difference (p = 0.9) between the removal of the intraradicular retainer using ultrasound (1.99 ± 0.62 mm) or using a rotating cutting instrument (1.62 ± 0.62 mm). Under these experimental conditions, it was possible to conclude that the degree of apical leakage was directly related to the alloy type, and it was present in both techniques used.

Bat flies (Nycteribiidae) of the order Diptera are highly specialized bloodsucking ectoparasites living on bats. The life-cycle of the bat flies emphasizes their obligate relationship with their hosts as they spend almost their entire life on bats. Upon mating, the female bat fly carries the larvae internally until the 3rd-instar when it deposits the larvae on the ceiling of the roost occupied by bats. The larvae then form a puparium. After 3-4 weeks the adult bat fly emerges from the puparium and starts searching for a host bat to colonize. Some of these ectoparasitic bat flies themselves are infected with an ectoparasitic fungus of the genus Arthrorhynchus (Laboulbeniales). Ascospores of the fungi attach themselves to the cuticle of the bat fly and develop a very conspicuous haustorium that penetrates into the soft tissues from where it presumably extract nutrition from the hemolymph of the bat flies. This interaction converts the fungus into a hyperparasite. Both the parasite and hyperparasite are obligates and cannot live separate from their hosts. This peculiar case of hyperparasitism remains highly unknown. The bat flies were collected in caves of Portugal, in maternity and hibernation bat seasons, and in the autumn migration period. The most common species of cave-dwelling bat species in Portugal is Miniopterus schreibersii, frequently parasitized with Nycteribia schmidlii and Penicillidia conspicua bat flies. We have studied the prevalence of the Laboulbeniales of the genus Arthrorhynchus in natural populations of bat flies. The site and position of the fungus on male and female bat flies unveils the mechanism of fungal transmission among bat flies, indicating that it occurs during mating behavior. This study is the starting point towards the understanding of this unique case of fungus-insect-vertebrate hyperparasitism interaction. See Suppl. material 1.
