AbstractLogistics providers have to utilize available capacities efficiently in order to cope with increasing competition and desired quality of service. One possibility to reduce idle capacity is to build coalitions with other players on the market. While the willingness to enter such coalitions does exist in the logistics industry, the success of collaborations strongly depends on mutual trust and behavior of participants. Hence, a proper mechanism design, where carriers do not have incentives to deviate from jointly established rules, is needed. We propose to use a combinatorial auction system, for which several properties are already well researched but little is known about the auction’s first phase, where carriers have to decide on the set of requests offered to the auction. Profitable selection strategies, aiming at maximization of total collaboration gains, do exist. However, the impact on individual outcomes, if one or more players deviate from jointly agreed selection rules is yet to be researched. We analyze whether participants in an auction-based transport collaboration face a Prisoners’ Dilemma. While it is possible to construct such a setting, our computational study reveals that carriers do not profit from declining the cooperative strategy. This is an important and insightful finding, since it further strengthens the practical applicability of auction-based trading mechanisms in collaborative transportation.

What is the impact of crime on the average individual in this country? What is the impact of the fear of crime on the quality of life in the United States? These questions are addressed in this article not from the point of view of an expert, or of an official in the criminal justice system, or of a victim of crime, but from that of an average person whose experience has included no direct encounter with crime of any kind. Those who have been victims of crime and those affected even indirectly by criminal behavior will react, naturally, with predictable concern; crime also has discernible effects on the attitudes and behavior of people generally, and this impact in turn has a corrosive effect on the quality of life in America.

Therapeutic recreation (TR) activities benefit the affect and behavior of persons with dementia. The authors examine the perceived utility of an Activity-in-a-Box methodology as part of a larger study examining the impact of group activities on persons with dementia. The box contained items such as a program protocol and materials adapted to the abilities of persons with dementia. This article reports about the perceptions of 10 TR staff concerning the utility of the Activity-in-a-Box format. Staff reported that materials were very useful and enumerated multiple benefits, including: enhancing therapists’ ability to engage participants in different activities, facilitating new types of activities for staff members to try, and a useful tool for training. The authors recommend further investment in enhancing the scope and the quality of Activities-in-a-Box materials.

This study attempted to discover and analyse the impact of violent online games on the players’ language and behavior as well as how these expressions might harm, intimidate, and damage others’ face. It is worth mentioning that online games become the young’s playground where they interact with others and may adopt a certain type of language and behavior.  As players engage in a competitive fight of characters, they use certain communicative styles to express their feelings and emotions, including impolite expressions. Hence, this paper looked into these expressions, their responses to those expressions, and the reasons behind them. In addition, this study identified whether there is any impact in choosing these impolite expressions. Moreover, these violent gaming can provide a good field of investigation because impoliteness is widely occurring in such situations, through which people from various cultures, ages and genders come in contact to fight each other, be uncivil, and criticize and damage the other’s face. Moreover, these games may even encourage certain harmful impolite terminology and aggressive behavior to inter the players ‘repertoire and become the language of everyday use. In gathering the data, impolite expressions were collected by participating in some battles involving abusive and impolite words. Based on the results obtained, the study reached some conclusions that Culpeper’s (2005) and Spencer-Oatey’s (2002 and 2005) models are applicable in the context of violent online games. There is a big tendency that young people adopt and use various impolite expressions according to their gender and their relations for many reasons. In addition, it is widely recognized that most players have limited politeness competence and directly reply to others’ impolite language with hostility. Finally yet importantly, positive impoliteness strategies are used more than the other models, whereas quality of face was the most damaged one in Spencer-Oatey model.

INTRODUCTION: Epilepsy is a disorder that results in abnormal activity in a group of neurons that may have significant impact on the normal cognitive processes and behavior. Temporal lobe epilepsy (TLE) is the most frequent form of partial epilepsy in adults, and hippocampal sclerosis (HS) the most common neuropathologic finding in patients with medically refractory TLE. Patients with TLE often present cognitive difficulties that may be determined by the effects of epileptic discharges and side of the lesion. And its consequence is that patients have poor effects on quality of life (QOL). PURPOSE: We report the relationship between neuropsychological assessment and QOL under the hypotheses that patients with worst results in neuropsychological assessment have poorer QOL assessed by the QOLIE-31. RESULTS: Regarding seizure frequency, 23 (46%) had had 1-5, 20 (40%) 6-10 and 7 (14%) more than 10 seizures/month. In relation to seizure types, 5 (10%) had had auras, 37 (74%) complex partial seizures and 8 (16%) partial evolving to generalized tonic-clonic seizures (GTCS). Neuropsychological evaluation had a positive correlation with QOLIE-31 domains. QOL evaluations had the worst scores in QOLIE-31 were in Cognitive Function (45.0) and Social Function (46.0). The best was Overall QOL (62.0). CONCLUSION: People with epilepsy have great impact on their QOL not only because of daily seizures but because of the impact seizures cause in their cognitive functions. TLE is an example of how refractory epilepsy can exterminate any possibilities of work, study and live in a society that discriminates someone with epilepsy who also presents cognitive decline.

Abstract Aim Several health organizations have been expressing concern about the amount of time children spend using electronic devices and about the benefits and damages of the use of touchscreen devices, such as smartphones or tablets, for the development and behavior of children under the age of 5. A systematic review was carried out in order to understand the impact of touchscreen device usage toward children’s development and behavior under the age of 5. Methods Using the PRISMA method, from a total of 6314 studies found in online databases, searched in English, between 01/01/2000 and 01/10/2018, 11 studies were selected for analysis. Results The results revealed that, in children under the age of 5, the damages of the use of touchscreen devices are superior to the benefits that may result, especially when there are more hours of screen time. More importance is given to the quality of the child-adult relationship and not to the use of touchscreen devices. Nevertheless, some studies emphasize some aspects that may reduce the negative effects, such as moderate use, less screen time, parental monitoring, and viewing educational programs in an academic environment. Conclusions Guidelines that should be given to parents about the use of touchscreen devices by children are discussed. The limitation of this study was the difficulty in finding studies directed to the desired age and type of electronic device. This may be taken as a potential cause of bias.

ABSTRACT Abnormal menstrual bleeding (AMB) is a common gynecological complaint. It may have serious repercussions on women's quality of life. Most of the studies on abnormal menstrual bleeding focus on the quantity of blood loss with little emphasis on the effect, it has on the quality of women's life. Recent research in the area of abnormal menstrual bleeding has recognized the importance of the ‘patient experience’ as an outcome that should be measured. So, it is very important to know about women's perception about the problem so that the healthcare professional can provide them appropriate care. The present study was undertaken to assess effect of AMB on various aspects of women's life and to assess their knowledge toward causes and management of AMB and its health impacts. Though majority of women know about abnormal bleeding as something serious, but still they lack in depth understanding of its consequences and various treatment modalities available. Significance for public research The article gives us valuable inputs regarding patient's viewpoint about abnormal uterine bleeding. Knowing the patients perceptions, their attitude toward abnormal menstrual bleeding and various social factors affecting it may be very helpful for the health professionals and researchers in knowing the impact of abnormal bleeding on quality of life and hence selecting the treatment strategies that will improve patient's satisfaction.

Suicide is a worldwide phenomenon and is a major problem in social and health care. For many decades, there has been a growing interest in developing suicide prevention strategies. Suicide is recognized as a serious, worldwide public health concern and has been proven to be the tenth leading cause of death worldwide. The approximate international burden of suicide is one million deaths a year and public awareness is needed to effectively prevent suicide. Suicide rates varyby region and country, and the risk of suicide varies according to gender, age, employment status and quality of physical and mental health. A considerable number of substantial studies have been conducted to investigate risk factors that predict suicidal ideation and behavior. In particular, studies have shown that demographic factors such as gender and age have been found to be essential risk factors associated with suicide. Numerous studies have also investigated the association between chronic medical disease and Greek financial crisis with the existence and increased risk of suicidal behavior. The cross-sectional study had the following objectives: 1) To evaluate mental stress, suicide beahavior, patients' illness perception, sence of coherence, resilienceand religiousness of patients with chronic medical diseases. The prospective study had the following objectives: 1) to assess the course of mental stress and quality of life of patients with chronic medical diseases during a semester 2) to identify the factors associated with suicide behavior in the overall sample but also separately in patients and in the control group 3) to identify factors for improving suicide beahior in patients and in the control group 4) to identify factors affecting the relationship of suicide behavior with perceived influence of financial crisis. In the cross-sectional study participated 821 subjects, 629 of whom were in the group of patients with chronic medical diseases and 129 in the control group. In the prospective study, 464 patients with chronic medical diseases and 110 healthy subjects participated in the first phase of the study, participated in the second assessment 6 months later. The data were collected through semi-structured psychiatric interview, as well as by completing questionnaires. The findings of the 150 study showed a high prevalence of major depressive disorder, suicidal ideation and behavior and Generalized Anxiety Disorder (GAD) in patients with chronic medical diseases visiting the University Hospital of Ioannina during the Greek financial crisis. At the same time, a significant proportion of the healthy sample had depressive symptoms, however smaller than the patient sample. In addition, the results ofcurrent research verify the association between chronic physical illness and comorbidity with major depressive disorder and suicidal behavior. In addition, analyses occurred six months after baseline found that all outcomes (ie, severity of depressive symptom, risk of suicide, quality of life relatedto health) were significantly improved. The results of the prospective study on factors related to suicidality during follow-up showed that psychiatric history was significantly associated with suicidality in the overall sample of patients and healthy subjects (control group) participated in the study. Specifically, the high RASS Suicide Score and the diagnosis of depression (PHQ> 10) at baseline seem to be positively correlated with suicide scores on the follow up. On the contrary, depression improvement is negatively related to suicide on follow up assessment. Regarding theimprovement of suicide in the patient sample, three variables were found statistically significant: RASS suicidality and PHQ-9 depression diagnosis at baseline, and improvement in depression measured with the PHQ-9 scale during 6 months. These variables are same with the variables identified as important for predicting suicidality in the second measurement after a 6-month follow-up throughout the study sample. In the healthy population sample, age, diagnosis of depression (PHQ>10), and lower RASS scores were found to be negatively correlated with improved suicidality. Finally, the most important new finding is that the impact of the current financial crisis is linked to the risk of suicide, but this correlation is moderated by the presence of a psychiatric disorder: the greater the impact of the crisis, the greater the risk of suicide only when a psychiatric disorder or generalized anxiety disorder is diagnosed. In this light, as the rates of depression, anxiety disorder, and suicide in patients with chronic medical diseases were significant in the present study,clinicians should be aware that referral for psychiatric intervention is important in patients with chronic medical diseases.

Attempts to improve the domestic quality of government often involve international arrangements and the fight against corruption is a prominent example. Since the 1990s, anticorruption pledges, international treaties, soft law arrangements, transnational advocacy campaigns, and other commitments have proliferated to control bribery and corruption in a range of contexts. This chapter surveys the literature on the emergence and characteristics of these various initiatives and provides an overview of what is known about their impacts on policy and discourse, law, and behavior. While empirical evidence on the impact of international anticorruption efforts is mixed, existing studies and directions for future research suggest that the quality of government in highly developed states is crucial when it comes to controlling transnational business bribery, money laundering, and other illicit financial flows.

In Poland, similarly as in the entire Europe, the quality of air is shaped primarily by communal-living sources and road transport. Due to the steadily increasing share of city residents in the general population, the issue of providing clean air will become a more significant problem for human health over the years, and therefore a stronger incentive to intensify the research. Hence, the key challenge faced by a modern society is to limit the emissions of harmful substances in order to minimize the impact exerted by transport on air pollution and health. Increasingly stringent emission standards are imposed on car manufacturers while on the other hand, the problem of drivers is being ignored namely their awareness of possibilities to reduce the emissions and the ways in which they can help protecting also their own health and life by applying the rules related to the concept of eco-driving in practice. The aim of this paper is to present differences in perception of eco-driving principles in two random and nation-wide surveys: one carried out in 2015 and the other in 2017. Initial conclusions show a major increase (49.4% to 53.2%) of eco-driving awareness among respondents in 2017 when compared to 2015.

Abstract Introduction In March 2020, an unprecedented number of individuals were confined to their homes in an effort to stem the spread of the novel Coronavirus (Covid-19), however the impact of this confinement on health and behavior is unknown. Long-duration confinement studies have found effects on homeostatic biology and neurobehavioral functions, including reduced sleep durations. This study evaluated how confinement due to Covid-19 has impacted health and stress through changes in sleep. Methods The Anonymous Survey on Confinement during the COVID-19 Pandemic was available online to any individual ≥18 years of age through the Penn Medicine Clinical Research webpage on May 14, 2020 and the data presented are through October 24, 2020. The survey collected self-reported information on demographics, the amount and quality of sleep, as well as ratings of health and stress. To determine the impact of confinement on these domains, participants were asked to answer questions relative to pre-confinement levels. To test associations between sleep amounts and sleep quality on health and stress, generalized linear models were used and adjusted for age, sex, and race. Results N=228 participants (n=180 female [79.0%]) were on average 45.0±17.1 years of age. During confinement relative to pre-confinement, 41.7% of participants reported sleeping more, 37.3% reported sleeping the same amount, and 21.0% reported less sleep, while 14.0% reported better sleep quality, 47.4% the same, and 38.6% worse quality of sleep relative to pre-confinement. Ratings of worse health during confinement were associated with both reduced sleep amount (β=0.695; P<0.0001) and worse sleep quality (β=0.532; P=0.0002). Lower stress ratings were associated with increased sleep amount (β=0.734; P=0.034), better sleep quality (β=1.396; P=0.0002), better health ratings (β=-0.079; P=0.0045). Conversely, worse sleep quality was associated with higher stress ratings (β=-1.086; P=0.0007). Conclusion The confinement resulting from the COVID-19 pandemic has impacted the amount and quality of sleep and good sleep may help to reduce stress and maintain health. These findings highlight the need to further examine how long-term confinement influences human health and behavior and warrant examining what factors or life-style behaviors promote resilience to the negative effects of confinement.
