Grottenolme Proteus anguinus (Laurenti, 1768) zeigen eine sehr geringe Fortpflanzungsrate, werden sehr alt und haben eine im Vergleich zum Menschen verzögerte Generationenfolge. Damit sind Olme Lebewesen für spannende evolutionsbiologische Fragestellungen, die sich um Populationswachstum drehen. Die vorliegende Arbeit zeigt auf, dass eine stabile Umwelt, wenig Krankheiten, das Fehlen von Fressfeinden und ausreichende Nahrungsressourcen evolutiv einen starken Einfluss auf das fehlende Populationswachstum beim Olm haben. Ein Vergleich mit dem Menschen eröffnet, neben der Bildung und dem Aufbrechen von Bräuchen, auch Wege naturgegebener Mechanismen, wie das Wachstum der Weltbevölkerung sich stabilisieren ließe. Der verzögerte Eintritt in die Reproduktion zeigt beim Grottenolm zudem einen positiven Effekt auf die Langlebigkeit. Human fish and human beings – European Cave Salamander Proteus anguinus (Laurenti, 1768) explains longevity and population growth Abstract: European Cave Salamanders, more specifically olms, show a low reproduction rate, reach methuselah ages and exhibit extended generation frequencies in comparison to humans. Olms are therefore considered an interesting study object for evolutionary questions about population growth. The paper discusses stable environment, good health, top predator position and continuous basic food supply as the key factors for stagnation of population growth in olms as well, if combined with education, as in humans. A late start of reproduction triggers in turn a positive impact on longevity.

As human beings God have given them the potential of emotion to do bad or good things. Totally eliminating emotion is also not good. Whereas on account of the emotion ones are eager to eat when they are hungry, they are sad, happy, have a sense of love and so on. So the most important thing is controlling and directing the emotion so that it becomes a guide toward good things. Fasting on Mondays and Thursdays  as part of refraining from any action contrary to the religious teachings will bring self-control, honesty, social awareness, the meaningfulness of life not do things that deviate from the teachings of Islam. Fasting could have a positive impact on a person's religiosity, but not all fasting could increase spiritual intelligence. Only fasting that is done with pure heart and soul will foster spiritual intelligence. Fasting that is done by involving conscience is the true one for being able to become an important instrument to purify the heart and soul. Fasting on Mondays and Thursdays will be able to improve the emotional and spiritual intelligence.

There may be so many negative consequences of stress for human beings and dissatisfaction among employees happens to be one of the major problems. It indicates negative feelings that individuals have regarding their jobs or its facets. On the other hand, social support is assumed to be mitigating the relationship between negative aspects of the work environment and job satisfaction. Job stress is said to be associated with job dissatisfaction as well as experience of strain. In view of the above, this study examined the role of job stress and social support in job satisfaction. The sample consisted of 30 school teachers from different school of Varanasi (U.P.). The job stress, job satisfaction and social support scales were administered on the participants. The responses of the participants were converted into scores for statistical analyses. The scores of participants on the scales were correlated. The findings revealed that job stress led to increased job satisfaction. It is against the proposed hypothesis and it appears as if the social support received by the participants is a factor behind it. Two of the four dimensions of social support were found to exert positive impact on job satisfaction but the other two dimensions were not found to be correlated with it. The findings are thoroughly discussed and interpreted.

Sustaining the development of car-sharing is considered an efficient way to counter environmental issues worldwide. Against this background, college students are recognized as a promising customer group of car-sharing service providers in China. However, the determinants that promote students’ willingness to use car-sharing services are rarely studied, and the uniqueness of college students in China in the context of car-sharing is justified. Therefore, this paper examines the key factors that affect Chinese college students’ adoption of car-sharing. An empirical study using samples from Dalian Maritime University was conducted, and survey data were collected via the Internet. Specifically, respondents’ socio-demographics were obtained, and their latent attitudes on car-sharing services were measured in terms of willingness to use car-sharing services, perceived usefulness, perceived ease of use and safety concerns. In addition, nine hypothetical travel scenarios were defined, and regarding each travel scenario, the respondents were asked to state whether they were willing or not to use car-sharing services. On this basis, a hybrid logit model was established to investigate the key factors that influenced the willingness to use car-sharing services. Aside from the common findings in line with previous studies, the results indicate that with the increase in the number of travel fellows, willingness to use car-sharing services went up. Furthermore, college students’ willingness to use car-sharing services was significantly affected by money costs rather than time costs. Additionally, college students in China are more likely to use car-sharing services during workday off-peak hours and weekends. Separately, among the respondents’ latent attitudes, only the perceived usefulness of car-sharing services was found to have a significant and positive impact on students’ willingness to use them. Relevant policy implications with regards to theoretical findings are also offered in this paper to car-sharing service providers in China.

Acute kidney injury (AKI) is a common complication in critically ill patients with an incidence of up to 50% in intensive care patients. The mortality of patients with AKI requiring dialysis in the intensive care unit is up to 50%, especially in the context of sepsis. Different approaches have been undertaken to reduce this high mortality by changing modalities and techniques of renal replacement therapy: an early versus a late start of dialysis, high versus low dialysate flows, intermittent versus continuous dialysis, anticoagulation with citrate or heparin, the use of adsorber or special filters in case of sepsis. Although in smaller studies some of these approaches seemed to have a positive impact on the reduction of mortality, in larger studies these effects could not been reproduced. This raises the question of whether there exists any impact of renal replacement therapy on mortality in critically ill patients—beyond an undeniable impact on uremia, hyperkalemia and/or hypervolemia. Indeed, this is one of the essential challenges of a nephrologist within an interdisciplinary intensive care team: according to the individual situation of a critically ill patient the main indication of dialysis has to be identified and all parameters of dialysis have to be individually chosen with respect to the patient’s situation and targeting the main dialysis indication. Such an interdisciplinary and individual approach would probably be able to reduce mortality in critically ill patients with dialysis requiring AKI.

This is the first published report concerning reproduction and survival using life table analyses of fertility and survival for Muscina stabulans maintained under laboratory conditions with artificial diets. The intrinsic rate of growth, reproduction rate and average generational time were obtained, suggesting a rapid population growth under these rearing conditions. These findings permitted the creation of time models of survival and oviposition, as well as a quantitative estimate of the adaptation capacity of this species.

<b>Abstract:</b> Human activities always produce trash. The amount of trash continues to grow in line with population growth and technological developments. Trash has become an environmental crisis due to a lack of awareness and in Indonesia little serious effort has been made to process trash properly. The importance of a serious effort of trash management and self-development as a real human being is nothing other than a struggle to restore harmony between Creator, human beings, and the whole of creation. This paper reflects on the reality of trash as well as taking up the views and habits of people who are little concerned about handling trash although they already feel the adverse impact of trash on the environment. This study analyses data and the information obtained through observation of the trash problem, supported by data from written sources . <b>Keywords:</b> Trash, environment, human development, ecological repentance <b>Abstrak:</b> Kegiatan manusia selalu menghasilkan sampah. Peningkatan jumlah sampah terus bertambah seiring dengan pertambahan penduduk dan perkembangan teknologi.

This article discusses the main points of the formation and development of the concept«demographic potential» used for the purposes of management and forecasting in a changing environment. The need for demographic potential as an instrumental, supporting notion arose when researchers began to examine possible effects of demographic processes and their impact on the structure and size of population in the future, i.e. build population projections and population development models. Historically, researchers studied demographic potential separately for each component of the overall population growth. Beginning of the study of fertility potential is associated with the name of R. E. Fisher, life potential — with the work of L. Hersch, migration capacity — with the works of J. Q. Stewart, G. K. Zipf, S. A. Staufer and W. Izard. Attempts to assess the joint effect of different components of the overall population growth were episodic. Only in the 30s of the twentieth century the integrated synthesis indicators began to be used for describing the demographic potential. One of the indicators for capacity of population reproduction may be net reproduction rate. Modern interpretations of the potential of changes in fertility and mortality, migration capacity have a wider purpose and filling than at the time of these concepts’ formation. Demographic potential in a narrow sense is the potential population reproduction, including changes in fertility and mortality; in a broader sense, it is the total potential of population — potential of reproduction and migration potential, including possible changes in the population size and structure due to births, deaths, immigration and emigration.

The internet is an essential and integral part of our lives, whether it's about looking for a meaning of a word, searching for a journal, shopping, or connecting to others. Human beings cannot think of life without the internet. Although it's having a positive impact, the negative side is there. Problematic internet use is defined as non-chemical or behavioral addictions, which involve human-machine interactions and can be harmful as it leads to numerous forms of psychological disorders. The chapter addresses various psychopathologies arising due to excessive internet use (e.g., problematic internet use, online gaming, online gambling, and compulsive cybersex). The chapter frames a strong theoretical background along with recent controversial issues related to the disorder. The chapter is delineated to acquaint readers with new concepts arising in clinical psychology that will help mental health professionals to be well equipped with skills required for the prevention and treatment of internet-related psychological disorders.

Today’s data and information management tools enable massive accumulation and storage of knowledge that is produced through scientific advancements, personal and corporate experiences, communications, interactions, and so forth. In addition, the increase in the volume of this data and knowledge continues to accelerate. The willingness and the ability to share and use this information are key factors for realizing the full potential of this knowledge scattered over many distributed computing devices and human beings. By correlating these isolated islands of knowledge, individuals can gain new insights, discover new relations (Sheth, Arpinar & Kashyap, 2003), and produce more knowledge. Despite the abundance of information, knowledge starvation still exists because most of the information cannot be used effectively for decision-making and problem-solving purposes. This is in part due to the lack of easy to use knowledge sharing and collective discovery mechanisms. Thus, there is an emerging need for knowledge tools that will enable users to collectively create, share, browse, and query their knowledge.
