Abstract Research on online engagement is abundant. However, most of the available studies have focused on a single course. Therefore, little is known about how students’ online engagement evolves over time. Previous research in face-to-face settings has shown that early disengagement has negative consequences on students’ academic achievement and graduation rates. This study examines the longitudinal trajectory of students’ online engagement throughout a complete college degree. The study followed 99 students over 4 years of college education including all their course data (15 courses and 1383 course enrollments). Students’ engagement states for each course enrollment were identified through Latent Class Analysis (LCA). Students who were not engaged at least one course in the first term were labeled as “Early Disengagement”, whereas the remaining students were labeled as “Early Engagement”. The two groups of students were analyzed using sequence pattern mining methods. The stability (persistence of the engagement state), transition (ascending to a higher engagement state or descending to a lower state), and typology of each group trajectory of engagement are described in this study. Our results show that early disengagement is associated with higher rates of dropout, lower scores and lower graduation rates whereas early engagement is relatively stable. Our findings indicate that it is critical to proactively address early disengagement during a program, watch the alarming signs such as presence of disengagement during the first courses, declining engagement along the program or history of frequent disengagement states.

BACKGROUND Postpartum depression (PPD) is linked to long-standing negative consequences for women and families. Virtual care applications present a solution to the challenge of recruiting large samples for genetic PPD research. OBJECTIVE This study evaluated the feasibility of using an iOS mobile application (PPD-ACT app) to collect genetic samples from Canadian women with current or past PPD. METHODS Women downloaded the PPD-ACT app to provide consent, phenotypic data, and if they met inclusion criteria, mailing information for a genetic sample. PPD was defined as: (1) Edinburgh Postnatal Depression Scale (EPDS) score of >12 at most severe episode, (2) onset in pregnancy or 0-3 months postpartum, and (3) no preterm birth or severe maternal or child illness. Latent class analysis (LCA) described PPD case phenotypes. Women self-reporting lifetime postpartum psychosis (PPP) were also asked to provide a DNA sample. RESULTS Of 797 women meeting PPD case criteria, 75.0% (n=598) agreed to be sent a DNA collection kit; 67.6% of whom (n=404) submitted a sample. Women (86.7% White) came from 11/13 Canadian provinces/territories, with a mean of 4.7 years (SD=7.0) since the PPD episode. LCA identified two PPD classes, clinically distinct by illness severity: (1) moderate severity (mean EPDS=18.5, SD=2.5; 8.6% with suicidality), and (2) severe (mean EDPS=24.5, SD=2.1; 52.8% with suicidality). 109 women self-reported a history of PPP (39 without PPD; 60.7% submitted DNA). CONCLUSIONS A mobile application rapidly collected data from women with relatively severe forms of PPD, an advantage for genetics where specificity is optimal, and may be feasible for collecting data from women with a history of the even more rare condition of PPP. Expanding the mobile platform options might increase accessibility as well as the diversity of the sample.

The profound changes within the Albanian society, including Albania, Kosovo and Macedonia, before and after they proclaimed independence (in exception of Albania), with the establishment of the parliamentary system resulted in mass spread social negative consequences such as crime, drugs, prostitution, child beggars on the street etc. As a result of these occurred circumstances emerged a substantial need for changes within the legal system in order to meet and achieve the European standards or behaviors and the need for adoption of many laws imported from abroad, but without actually reading the factual situation of the psycho-economic position of the citizens and the consequences of the peoples’ occupations without proper compensation, as a remedy for the victims of war or peace in these countries. The sad truth is that the perpetrators not only weren’t sanctioned, but these regions remained an untouched haven for further development of criminal activities, be it from the public state officials through property privatization or in the private field. The organized crime groups, almost in all cases, are perceived by the human mind as “Mafia” and it is a fact that this cannot be denied easily. The widely spread term “Mafia” is mostly known around the world to define criminal organizations.The Balkan Peninsula is highly involved in these illegal groups of organized crime whose practice of criminal activities is largely extended through the Balkan countries such as Kosovo, Albania, Macedonia, Serbia, Bosnia, Croatia, Montenegro, etc. Many factors contributed to these strategic countries to be part of these types of activities. In general, some of the countries have been affected more specifically, but in all of the abovementioned countries organized crime has affected all areas of life, leaving a black mark in the history of these states.

BackgroundCellulitis is a common painful infection of the skin and underlying tissues that recurs in approximately a third of cases. Patients’ ability to recover from cellulitis or prevent recurrence is likely to be influenced by their understanding of the condition.AimTo explore patients’ perceptions of cellulitis and their information needs.MethodMixed methods study comprising semi-structured, face-to-face interviews and cross-sectional survey, recruiting through primary care, secondary care and advertising. Adults aged 18 or over with a history of cellulitis (first or recurrent) were invited to complete a survey, take part in an interview or both. Qualitative data was analysed thematically.ResultsThirty interviews were conducted between August 2016 and July 2017. Qualitative data revealed low prior awareness of cellulitis, uncertainty around diagnosis, concern/surprise at the severity of cellulitis, and perceived insufficient information provision. People were surprised they had never heard of the condition and that they had not received advice or leaflets giving self-care information. Some sought information from the internet and found this bewildering. Two hundred and forty surveys were completed (response rate 17%). These showed that, while most people received information on the treatment of cellulitis (60.0%, n = 144), they reported receiving no information about causes (60.8%, n = 146) or prevention of recurrence (73.3%, n = 176).ConclusionThere is a need for provision of basic information for people with cellulitis, particularly being informed of the name of their condition, how to manage acute episodes, and how to reduce risk of recurrence.

This chapter presents the history of the development of the concept of phase space. Phase space is the central visualization tool used today to study complex systems. The chapter describes the origins of phase space with the work of Joseph Liouville and Carl Jacobi that was later refined by Ludwig Boltzmann and Rudolf Clausius in their attempts to define and explain the subtle concept of entropy. The turning point in the history of phase space was when Henri Poincaré used phase space to solve the three-body problem, uncovering chaotic behavior in his quest to answer questions on the stability of the solar system. Phase space was established as the central paradigm of statistical mechanics by JW Gibbs and Paul Ehrenfest.

AbstractBaffin Bay hosts the largest and most productive of the Arctic polynyas: the North Water (NOW). Despite its significance and active role in water mass formation, the history of the NOW beyond the observational era remains poorly known. We reconcile the previously unassessed relationship between long-term NOW dynamics and ocean conditions by applying a multiproxy approach to two marine sediment cores from the region that, together, span the Holocene. Declining influence of Atlantic Water in the NOW is coeval with regional records that indicate the inception of a strong and recurrent polynya from ~ 4400 yrs BP, in line with Neoglacial cooling. During warmer Holocene intervals such as the Roman Warm Period, a weaker NOW is evident, and its reduced capacity to influence bottom ocean conditions facilitated northward penetration of Atlantic Water. Future warming in the Arctic may have negative consequences for this vital biological oasis, with the potential knock-on effect of warm water penetration further north and intensified melt of the marine-terminating glaciers that flank the coast of northwest Greenland.

AbstractCVD diamond combines attractive properties for the fabrication of detection devices operating in specific environments. One problem that remains critical for device stability is the presence of defect levels that alter the detection performances, and the detection characteristics often appear as they are very depending on time, temperature, and history of the preceding irradiations.One issue we have proposed is to adapt one technique that is commonly used for time of flight spectroscopy in order to maintain a uniform electric field in the probed device, and based on the synchronisation of the device bias with the period of the excitation source. This can be applied to several types of detection applications, as long as we can rely on periodical triggering in order to synchronise the device polarisation. We apply it here to a LINAC electron accelerator used for photon pulse generation at the frequency of 25Hz. The result is a remarkable improvement of the performance of a polycrystalline diamond detector that exhibits a particularly defective response when used in the steady state excitation, to reach that of a perfectly stable and reproducible device response in the pulsed mode. We claim this method to be applicable to several types of excitations and particularly to present a high interest for monitoring accelerator sources, e.g. for medical dosimetry applications.

ObjectivesPrimary care records have traditionally served the needs and demands of clinicians rather than those of the patient. In England, general practices must promote and offer registered patients online access to their primary care record, and research has shown benefits to both patients and clinicians of doing so. Despite this, we know little about patients’ needs and expectations regarding online access to their record. This study explored what patients and carers want from online access to their electronic primary care health record, their experiences of using it, how they would like to interact with their record and what support they may need.DesignFocus groups and semistructured interviews using purposive sampling to achieve a good sociodemographic spread. Interviews were digitally audiorecorded, transcribed and coded using an established thematic approach.SettingFocus groups and interviews were conducted in community settings in the UK.ParticipantsFifty-four individuals who were either eligible for the National Health Service Health Check, living with more than one long-term condition or caring for someone else.ResultsParticipants views regarding online access were categorised into four main themes: awareness, capabilities, consequences and inevitability. Participants felt online access should be better promoted, and suggested a number of additional functions, such as better integration with other parts of the healthcare system. It was felt that online access could improve quality of care (eg, through increased transparency) but also have potential negative consequences (eg, by replacing face to face contact). A move towards more online records access was considered inevitable, but participants noted a need for additional support and training in using the online record, especially to ensure that health inequalities are not exacerbated.ConclusionsDiscussions with patients and carers about their views of accessing online records have provided useful insights into future directions and potential improvements for this service.

Breast cancer (BC) remains complex for women both physically and psychologically. The objectives of this study were to (1) assess the evolution of the main sequelae and treatment two and five years after diagnosis in women with early-stage breast cancer, (2) explore patterns of sequelae associated with given sociodemographic, clinical, and lifestyle factors. The current analysis was based on 654 localized BC patients enrolled in the French nationwide longitudinal survey “vie après cancer” VICAN (January–June 2010). Information about study participants was collected at enrollment, two and five years after diagnosis. Changes over time of the main sequelae were analyzed and latent class analysis was performed to identify patterns of sequelae related to BC five years after diagnosis. The mean age (±SD) of study participants at inclusion was 49.7 (±10.5) years old. Six main classes of sequelae were identified two years and five years post-diagnosis (functional, pain, esthetic, fatigue, psychological, and gynecological). A significant decrease was observed for fatigue (p = 0.03) and an increase in cognitive sequelae was reported (p = 0.03). Two latent classes were identified—functional and esthetic patterns. Substantial sequelae remain up to five years after BC diagnosis. Changes in patient care pathways are needed to identify BC patients at a high risk.
