A New Species

Klimakodesmus Carl, 1932 is briefly redescribed, rediagnosed, and shown to be an oligotypic genus endemic to southern India and distinct from the particularly similar genus Pyrgodesmus Pocock, 1892, monobasic and endemic to Sri Lanka, by several important features of peripheral and, especially, gonopodal structure. A new species, Klimakodesmus bilobocaudatus sp. nov., is described from Kerala state, India, differing from the sole accepted, and type species K. gravelyi Carl, 1932, from Tamil Nadu state, primarily by the laterally trilobate paraterga, the caudally more deeply bilobate mid-dorsal keel on ring 19, and certain minor details of the gonopodal structure.

The genus Martensopoda gen. nov. is established for two species from South India with distinct and apomorphic features in their copulatory organs. A cymbial spur in the male copulatory organs is reported the first time in the Sparassidae. The embolus’ loop — unique to Heteropodinae — is oriented transversally to the plane of the alveolus. Females exhibit spirally coiled copulatory openings similar to those of Spariolenus, but with a posterior pit at the median septum and with lateral loops of the internal duct system. Martensopoda transversa sp. nov. is described from Cardamon Hills in Kerala State (male, female), Martensopoda minuscula (Reimoser 1934) comb. nov. is known only from females and is recorded from Palni Hills, Tamil Nadu State.

Impatiens megamalayana is a recently described balsam from the Megamalai hills of the Western Ghats in Tamil Nadu state. This is a small, annual herb with ridged stem, often distributed in open, wet, rocky grasslands above 1,000 m elevation. The plant considered endemic to the Megamalai hills of Tamil Nadu is recently located in the Urumbikkara hills of Idukki district in Kerala state, which is about 120 km away from its original locality. Urumbikkara is an emerging tourist destination in central Kerala and the newly located populations of the plant are outside protected forest areas and are facing severe threat due to anthrapogenic activities. A detailed description, photographs and distribution maps are provided to facilitate easy identification of the plant in the field. An updated checklist of the genus Impatiens in Kerala state is also furnished for future reference.

Abstract Fertility variation was studied in two clonal seed orchards (CSO) of teak in four consecutive years (2003-2006). Both orchards were raised in 1976 with grafts of phenotypes selected for growth and form. The seed orchards of CSO I (Topslip, Tamil Nadu State) and CSO II (Walayar, Kerala State) have 15 and 20 clones, respectively, with 13 common clones. The proportion of flowering ramets was generally low ranging from 16 to 53% across years. The best fruit yield during the study period was around 18 kg ha-1 in CSO I and 17 kg ha-1 in CSO II. Highly significant clonal variation and clone by year and clone by site interactions were observed for fertility traits. The clonal contribution was more skewed in poor flowering years than in abundant flowering years and in CSO II than in CSO I. Broad sense heritability for flower and fruit production per tree was low to moderate (0.16 to 0.55). Flower and fruit production by individual ramets in successive years were positively correlated. Correlations between reproductive and growth traits were generally low, but correlation was strong between flowering and fruiting. Fertility variation and group coancestry were higher in poor flowering years than in abundant years and in CSO II than CSO I. Restricting seed collection to abundant flowering years, adjusting ramet number to balance contribution of clones and mixing of seeds from successive years are suggested to reduce relatedness among orchard progeny. The usefulness of low input breeding options for teak like seed production areas are also discussed.

Labour Turnover

Job satisfaction is an important factor for employees working in formal and informal sector. The job is small or big, permanent or temporary, risky or non-risky, job satisfaction is important. It is the mental feeling which drives the employees to excel. Job satisfaction is a combination of psychological, physiological and environmental circumstances. A satisfied employee is a contented and happy human being. The labour turnover depends upon job satisfaction. Even highly paid employees quit the job when they are not satisfied with the job. Road transportation in Tamilnadu is growing day by day. Job stress in the road transportation is very high due to increase in number of vehicle playing on the road and heavy traffic. The drivers and conductors working in public transport corporation are suffering from high job stress. If drivers and conductors are not satisfied with their job which leads to mental stresses and affects the productivity and also creates accidents. In this present study the researchers made an attempt to study the level of job satisfaction among the drivers and conductors who are working in the Tamilnadu State Transport Corporation (TNSTC). The study reveals the expectations of drivers and conductors working in TNSTC with regards to the attributes like salary, promotion and fringe benefits etc., are satisfactory and not detrimental.

Background and Objective: The causal role of maternal nutrition in orofacial clefts is uncertain. We tested hypotheses that low maternal vitamin B12 and low folate status are each associated with an increased risk of isolated cleft lip with or without cleft palate (CL±P) in a case–control study in Tamil Nadu state, India. Methods: Case-mothers of CL±P children (n = 47) and control-mothers of unaffected children (n = 50) were recruited an average of 1.4 years after birth of the index child and plasma vitamin B12, methylmalonic acid (MMA), total homocysteine (tHcy), and folate were measured at that time. Logistic regression analyses estimated associations between nutrient biomarkers and case–control status. Results: Odds ratios (ORs) contrasting biomarker levels showed associations between case-mothers and low versus high plasma vitamin B12 (OR = 2.48, 95% CI, 1.02-6.01) and high versus low plasma MMA, an indicator of poor B12 status (OR = 3.65 95% CI, 1.21-11.05). Case–control status was not consistently associated with folate or tHcy levels. Low vitamin B12 status, when defined by a combination of both plasma vitamin B12 and MMA levels, had an even stronger association with case-mothers (OR = 6.54, 95% CI, 1.33-32.09). Conclusions: Mothers of CL±P children in southern India were 6.5 times more likely to have poor vitamin B12 status, defined by multiple biomarkers, compared to control-mothers. Further studies in populations with diverse nutritional backgrounds are required to determine whether poor maternal vitamin B12 or folate levels or their interactions are causally related to CL±P.

The Cost

Groundwater depletion is experienced in several districts of Tamil Nadu state and Coimbatore district is heading in that direction. The average well failure rate is 47% for open wells and 9% for bore wells. The total cost of depletion for new wells varies from Rs 1,999 per ha to Rs 90,975 per ha. The electricity subsidy to the farmers has varied from Rs 22,621 per ha for coconut growers to Rs 25,498 per ha for banana growers as on 2004. The cost of irrigation per cubic metre (m3) is less on large farms. The average net return with free electricity varies from Rs 0.14 per m3 to Rs 1.38 per m3 and is drastically reduced when electricity is priced at an economic cost, i.e. Rs −1.15 to Rs −0.14 per m3. The shift in cropping pattern towards high value crops helped the farmers to some extent to bear the cost of externalities arising out of depletion. The social cost caused by groundwater overdraft is about Rs 554.3 million, which may increase when the well density increases further. Suggested policy options are to change the cropping pattern to less water-consuming crops, to invest in watershed development activities, to change inefficient pumpsets and to adopt well spacing norms.

The study was conducted to identify the most difficult topic in elementary teacher education first-year social science curriculum as perceived by the student-teachers by using survey research design. The study also investigated the underlying reasons responsible for the student-teachers' difficulties in learning different topics. 218 student-teachers were selected using convenience sampling technique from five District Institutes of Education and Training (DIET), in Tamil Nadu State (India) for the study. The instrument used for data collection was a checklist designed by the researchers to elicit information from the student-teachers. The data collected were analysed using frequencies and percentages. The results showed that the topic namely, 'Reading the Globe, Maps and Atlas' was perceived as the most difficult topic in social science curriculum. The results also showed that teaching the topic without using the maps, lack of previous knowledge about the maps, the existence of vague concepts, heavy content load, and lack of interest and motivation to learn map concepts were the main reasons responsible for the student-teachers' difficulties in learning the topic.
