The present study on the influence of disturbance in the dominated grassland near Bharathiar University, Coimbatore was studied over a period of one year from September, 2014 to August, 2015. The study was made during three seasons such as winter, summer and rainy so as to find out the seasonal changes as influenced by disturbance. The studied grassland is a semi-arid community containing most number of mesophytes with few xerophytes. To study the impact of disturbance, two sites such as undisturbed and disturbed ones spread over an area of 10 and 12 ha respectively were selected in the grassland. The floristic analysis showed that the undisturbed community was registered with 71 species and the disturbed community with 51 species. The family, Poaceae was represented by the high number of 14 and 13 species respectively in undisturbed and disturbed communities. Of the 71 species encounted, a sizablenumber of 66 species (92 %) harbour medicinal uses. It indicates that the study site was a potential habitat of medicinal plants with wide diversity. The quantitative ecological characters have been varied widely between the two sites due to the influence of disturbance. The resource apportionment for various species present in both study sites indicates that the grass, Brachiaria ramosa shared higher amount of resources than any other species present in the communities. The study suggested that the studied Brachiaria ramosa dominated grassland near Bharathiar University must be given conservation priority to protect the valuable medicinal species.

Plants are important in traditional Inuit life. They are used for food, tea, medicine, etc. Based on semi-structured interviews with 35 informants, we documented and compared plant names and uses in Kangiqsualujjuaq, Nunavik, and in Nain, Nunatsiavut. Plant names and uses were expected to be similar between communities owing to common boreal–subarctic environments and cultural ties. Both communities reported the same number of taxa, with equivalent proportions of vascular and nonvascular plants, growth forms, use categories, and medicinal uses. Forty-three species were used in each community, for a total of 78 species from 39 families. Despite a high overlap in species distributions, only 35% of nonvascular and 56% of vascular species were used in both communities. Correspondence was higher at the family level (64% of nonvascular and 75% of vascular families shared). The Ericaceae family was the most used, followed by Rosaceae. Thirteen of 30 medicinal species were shared between communities. There was a low correspondence regarding the conditions for which the medicinal species were used. Edible taxa were shared the most (52%). Plant uses unique to either Nain or Kangiqsualujjuaq may reveal separate bodies of traditional knowledge, or may reflect an overall loss of ethnobotanical knowledge in the Subarctic due to recent lifestyle changes.

On average, children and adults in developed countries consume too little water, which can lead to negative health consequences. In a one-year longitudinal field experiment in Poland, we compared the impact of three home-based interventions on helping children and their parents/caregivers to develop sustainable increased plain water consumption habits. Fluid consumption of 334 children and their caregivers were recorded over one year using an online specific fluid dietary record. They were initially randomly allocated to one of the three following conditions: Control, Information (child and carer received information on the health benefits of water), or Placement (in addition to information, free small bottles of still water for a limited time period were delivered at home). After three months, half of the non-controls were randomly assigned to Community (child and caregiver engaged in an online community forum providing support on water consumption). All conditions significantly increased the water consumption of children (by 21.9-56.7%) and of adults (by 22-89%). Placement + Community generated the largest effects. Community enhanced the impact of Placement for children and parents, as well as the impact of Information for parents but not children. The results suggest that the family setting offers considerable scope for successful installation of interventions encouraging children and caregivers to develop healthier consumption habits, in mutually reinforcing ways. Combining information, affordances, and social influence gives the best, and most sustainable, results.

In this article, the results of research on the cultivation of patty pan squash in the climatic conditions of Uzbekistan, Planting for different periods and its growth, development, yield, as well as the impact of weather conditions were presented. Squash is a one-year plant of the family of zucchini, mainly shrub, rarely found in the form of a whip. The results showed that average yield of “White-13” control was 16 tons/ha, and it was 17 tons/ha in “Solnyshko”. Furthermore, “NLO White” and “Umberall” had a high yield compared to the other varieties and hybrids, accounted for 15 tons/ha and 15.1 tons/ha, respectively. The highest average temperature during seed germination was found in 16 august, which was 30.3°C, whereas the lowest average temperature was 18.6°C in 1st April. The results showed that 4 days were required to reach 10% of seed germination in the period April 16 and May 1, however, 10% of seed germination in July 1 and 16th took 6 days. Furthermore, the least days for 75% of seed, germination was observed in the period of May 1, accounted for 8 days, and the rest of the period was the same.

The discussions surrounding imprisonment in response to crime in society has traditionally been on deterrent. A latent function of incarceration is the impact that a prison sentence has on the family of prisoners. Not much attention has been given to the spiral effect on families during incarceration. For example, in the United States, with increasingly harsh sentences being served in prisons in remote locations, severe hardships fall upon inmates and their families. The present study explores the ways in which Finland has sought to reduce the negative impact of a prison sentence on both inmate and family members. The study is based on one year of participant observation in an “open prison” in Finland, and interviews and observations with inmates and their families (numbers of inmates and families observed). Two questions that guide this research are: 1) What problems arise due to the incarceration of a family member? 2) What strategies are employed to respond to these problems? For example, having served times in prison reduces ex-prisoners' marriages as marriages does prevent recidivism. In other words, wives often instilled discipline in their partners in such a way to avoiding deviant behaviour. The open prison in Finland does reduces ill-mannered treatment of inmate partners by prison staffs during visits, reduces expensive collect calls, and the long waiting times for visitations, etc.

Abstract The study about the resilience of Rubiaceae to the influence of anthropogenic factors was conducted along the altitudinal gradient of 300–3900 m asl. in Western Bhutan. The survey covered three types of forest, categorized based on the prevalence of anthropogenic disturbances and assessed the diversity of Rubiaceae species in each forest type. The study recorded a total of 54 Rubiaceae species belonging to 41 genera from the study sites. The high diversity of Rubiaceae in the intermediately disturbed forest as revealed by Simpson and Shannon-Wiener diversity analysis and further strengthened by a between-group one-way ANOVA analysis contradicts the presumed description of Rubiaceae as ecologically sensitive. The wider adaptability range exhibited by Ceriscoides (Hook.f.) Tirvendadum, Himalrandia Yamazaki, Uncaria Schreber, and Leptodermis Wall. showing presence in all the forest categories indicates a higher survival rate of these genera. On the contrary, the species showing a higher rate of confinement to a specific habitat bears higher risk of extinction due to ever-rising anthropogenic disturbances. As such, an exhaustive research assessing the impact of different categories of anthropogenic factors on different species of Rubiaceae is required to understand the overall resilience of the family to the anthropogenic disturbances.

This retrospective study involved a 20% quota, age and sex stratified sample of people over 16 years of age, presenting to a group medical practice over a period of one year (N = 1568). A standardised, computer-scored, self-report questionnaire was administered. The response rate was 98.3%. 42% of respondents had travelled outwith the UK in the previous year. Of those, 42% had become ill whilst abroad. In 20.5% of cases the illness settled without treatment. However, 26% of the patients required consultation with a doctor whilst abroad and 48.4% of those becoming ill required further attention from the family doctor on return home. 5% of ill travellers were admitted to hospital abroad. 8% of all travellers did not have medical insurance cover. A large and significant population of travellers become ill whilst abroad, and travel-acquired illness has a large impact on general practice, with 1 in 5 travellers seeking GP consultation on return home. Improved practice-generated pre-travel health advice might decrease this burden on primary care.

The impact of severe injury and disability extends beyond the. injured person to the family, friends and general society. One group of severely disabled, the spinal cord injured, increases at an estimated 10,000 cases per year. These clients have been difficult and expensive to rehabilitate. To meet the needs of hard-pressed rehabilitation programs, new concepts and approaches to rehabilitation must be researched. One response to these needs is the use of the family as an adjunct to the rehabilitation process. A family involvement program for spinal cord injured, developed at Georgia Warm Springs Rehabilitation Complex, Warm Springs, focuses on both process and outcome variables in four major areas: medical, social, psychological and vocational.A four stage adaptation process was identified during work with spinal cord related patients. The initial stage, Anxiety, usually occurs within the first nine months post injury; the second stage, Accommodation, occurs between the tenth and twenty-fourth months; and the third stage, Assimilation, occurs after the second year and continues for a lifetime. A fourth stage, Reflux, can occur at any time and is a regression to an earlier stage.Allowing sufficient time for the adaptation process is essential if vocational rehabilitation is to become more effective with the spinal cord injured. An analysis of time post injury and successful completion of vocational evaluation and/or training (E/T) programs indicates patients injured longer than one year at entry into the programs have a greater probability of completing E/T than do patients injured less than one year at the time of admission to the programs.This research was sponsored in part by Grant #12-P-57897 from the Rehabilitation Services Administration, Department of Health, Education and Welfare, Washington, D.C.
