Mental Health Factors and Teaching Behaviors among Low-Income Hispanic Mothers
Authors: Planos Ruth , Zayas Luis H. , Busch-Rossnagel Nancy A.
Published: April 2013

The relationships among anxiety, depression, parenting stress, social support, and teaching behaviors were studied in a group of 101 low-income Dominican and Puerto Rican mothers with children in Head Start The two groups of mothers showed high levels of depression, anxiety, and parenting stress but did not differ significantly from each other. Puerto Rican mothers reported more social support than did Dominican mothers. Surprisingly, neither anxiety nor depression was significantly associated with social support Both groups used more directive, modeling, and visual cues than other behaviors in their teaching. Dominican mothers used more modeling than Puerto Rican mothers, who used more praise and inquiry. Anxious and depressed mothers also used more negative feedback, directives, and modeling. Those with high parenting stress used less inquiry and praise and more modeling. These findings inform clinical and educational interventions with parents and children.
Working with Noncustodial Mothers
Authors: Greif Geoffrey L.
Published: April 2013

Mothers who live apart from their children are often mistreated and misunderstood. Clinicians are increasingly called upon to treat this growing population. The author describes some of the key issues facing these mothers: money and child support, visitation, relations with the father, relations with the child, court involvement, and the impact of the social system. Suggestions for assisting them in a therapeutic relationship are offered.

Families and Schools Together (FAST): Integrating Community Development with Clinical Strategies
Authors: McDonald Lynn , Billingham Stephe , Conrad Tammy , Morgan Arthur , Nancy O , Payton Estella
Published: April 2013

Families and Schools Together (FAST) is an early-intervention/prevention, collaborative, school-based, multifamily family-support program for elementary school children who have been identified by their teachers as having behavior problems. The program integrates concepts and practices of community organizing with effective clinical techniques based on family therapy and play therapy. Parent–professional partnership is used to engage low-income and isolated families into the eight-week program. Process and outcome evaluation indicate that children show statistically significant improvements in conduct disorder, anxiety/withdrawal, and attention span over time. In addition, two-year follow-up data suggest that child-functioning gains are maintained and that FAST parents become more involved at school, regularly see their FAST friends, begin employment after being on welfare, return for further education, and become involved in the community.
Process-Psychodynamic Groups for Men who Batter: A Brief Treatment Model
Authors: Browne Kevin O. , Saunders Daniel G. , Staecker Kathryn M.
Published: April 2013

The prevailing method of working with men who batter is through structured psychoeducational groups and cognitive-behavioral therapy. The authors contrast the assumptions of cognitive-behavioral with those of process-psychodynamic approaches in working with men who batter. They describe a process-psychodynamic treatment model that was implemented at an abuser-treatment program. The major phases of the group process are illustrated with excerpts of group dialogue.
Including Children in Divorce Mediation and Education: Potential Benefits and Cautions
Authors: Gentry Deborah B.
Published: April 2013

Research measuring the effectiveness of divorce-mediation services and divorce-education programs shows that these services and programs help minimize the negative impact of parental divorce on children. The author discusses the benefits of including children in either intervention, concluding that practitioners who facilitate children's communication regarding their perceptions of parental divorce and its aftermath must manage this task with sensitivity and care.
Social Workers' Perceptions and Practice regarding Grandparents in Families of Children with a Developmental Disability
Authors: Findler Liora , Ben-Ari Orit Taubman
Published: April 2013

This study examined Israeli social workers' knowledge and practice concerning grandparents of children with disabilities. Eighty-one social workers providing services to families of children with disabilities responded to a 31-item questionnaire tapping demographic and professional background, knowledge of structural and functional aspects of grandparents' support, and actual practice with grandparents. The results showed that social workers recognize the significant and stable role grandparents play in the network of parents of children with disabilities. The findings also indicated that social workers believe that while parents need mostly emotional support from grandparents, they actually receive primary instrumental support, which contributes to mothers' adjustment more than it does to fathers' adjustment. As to actual practice, social workers report rarely involving grandparents in professional activities. Moreover, many social workers show no interest in obtaining more professional training in this area. The findings present a challenge to the social work profession to be more attentive to the significant family resource of grandparents in families of children with disabilities.
Service Needs of Relative Caregivers: A Qualitative Analysis
Authors: Davidson Beverly
Published: April 2013

Research indicates that kinship care in the child welfare system is increasing each year. Most child welfare agencies, however, do not provide adequate services to relative caregivers. The needs assessment presented here analyzed the service needs of a representative sample of relative caregivers at Lucas County Children Services in Toledo, Ohio. Field interviews were used to gather qualitative data. Results indicated that relatives needed tangible items such as beds, food, and clothing in the initial stages of placement. Ongoing needs included information regarding case progress and system procedures, respite, day care, and counseling for the child. The relatives recommended developing a kinship advisory council to assist the agency in policymaking and a respite program for relative caregivers.
Foster Parents' Attitudes toward Birth Parents and Caseworkers: Implications for Visitations
Authors: Erera Pauline I.
Published: April 2013

This study examines the behaviors and attitudes of 324 israeli foster parents toward birth parents and caseworkers. Although the foster parents generally expressed positive attitudes toward both birth parents and caseworkers, their contacts with both were minimal. Most foster parents did not encourage mutual visitation, were generally not involved in the birth parents' lives, and felt that the foster child belonged to them more than to the birth parents. Implications for visitation and reunification are discussed.
Violence and Aggression Directed toward Human Service Workers: An Exploratory Study
Authors: Shields Glenn , Kiser Judy
Published: April 2013

This study examined the type and extent of psychological aggression and physical violence experienced by 171 human service workers in four Midwestern rural communities and an in urban children services agency. Worker interviewing skills were also studied since the authors believed that appropriate interviewing skills could influence worker–client relationships in a positive manner, thus reducing the potential for violence. Data showed that there were some differences in the amount and intensity of client violence between rural and urban settings, although all workers were routinely subjected to psychological aggression. In addition, some workers were physically assaulted. In spite of constant threats, workers displayed professional demeanor that may diminish threats and reduce violence. Implications for policy and training concerning workplace violence in social service agencies are discussed.
Mothers of Adults with Mental Retardation: Is Race a Factor in Perceptions of Burdens and Gratifications?
Authors: Valentine Deborah P. , McDermott Suzanne , Anderson Dinah
Published: April 2013

The results of this research comparing the perceptions of burdens and gratifications of African American families and Caucasian caregivers of adult sons and daughters with mental retardation indicate that African American families are more likely to provide care within their homes. Regardless of in-home or out-of-home placement, however, African American mothers reported greater satisfaction and more intimacy with their sons and daughters with mental retardation and less burden and conflict than Caucasian mothers. Implications for social work practice and policy are suggested.
Psychosocial Concerns and Strengths of Women with HIV Infection: An Empirical Study
Authors: Gillman Ruth R. , Newman Bernie S.
Published: April 2013

The authors examine the psychosocial concerns, needs, and strengths of 67 adult women living with HIV in the Philadelphia area. Personal interviews revealed that the majority of women in the study were nonwhite mothers who relied on public assistance, had a drug-abuse history, and had a T-cell count less than 500/mm. More than half reported some utilization of social services (i.e., social work case management, support groups, drug treatment). Informal supports tended to come from extended family, friends, parents, and partners. Financial concerns and housing were more often ranked as one of the three primary concerns than was HIV disease. Many respondents were able to use their HIV diagnosis to reestablish priorities, especially with regard to their parenting roles, relationships, and drug use. Implications for social services are suggested.
The Responsibilities of Fatherhood as Perceived by African American Teenage Fathers
Authors: Allen William P. , Doherty William J.
Published: April 2013

The experience of adolescent fatherhood was explored through in-depth interviews. Ten African American teenage fathers from a midwestern city were asked to describe what being a father meant to them. The subjects discussed their perceptions of fatherhood and described some of the obstacles to meeting their paternal aspirations. Key themes included the subjects' desire to be actively involved with their children and the critical influence of the subjects' experiences with their own fathers. Strategies for working with adolescent fathers are also presented.
Normative Development in Transracial Adoptive Families: An Integration of the Literature and Implications for the Construction of a Theoretical Framework
Authors: Frasch Karie M. , Brooks Devon
Published: April 2013

Research on transracial adoption is limited by its overreliance on atheoretical research and the examination of children as the primary unit of analysis. There is also a significant lack of integration of approaches and empirical findings from disparate yet relevant literature. To better understand transracial adoption, this paper reviews and integrates the literature and offers a conceptual framework that can be used to examine the normative development of transracial adoptive families. Implications for practice and research are provided.
Human Development and Adversity in Ecological Perspective, Part 2: Three Patterns
Authors: Gilgun Jane F.
Published: April 2013

This article, part 2 of a study that sought to delineate processes leading to good and poor outcomes among individuals who have experienced childhood adversities, uses a life-history interview method to report on three patterns of development found under conditions of adversity: the model of the wounded well, a social-deficits model, and a social-assets model. Some major developmental processes that distinguished those who turned out well from those who did not turn out well were long-term, close personal relationships with peers and adults who modeled prosocial behaviors and values; emotional expressiveness and responsiveness to others; and feeling part of and at home with something outside themselves. This research demonstrates the importance of increasing protective factors and decreasing risk processes.
The Impact of Major Events on the Lives of Family Caregivers of Children with Disabilities
Authors: McDonald Thomas P. , Couchonnal Graciela , Early Theresa
Published: April 2013

The authors examine the family caregiving experience among families with children with severe emotional disabilities from a perspective that recognizes the importance of the family's views and feelings. This viewpoint anticipates the occurrence of both positive and negative experiences and seeks to illuminate the caregiving process from the perspective of outcomes achieved. Family caregivers of 164 children with serious emotional disorders were asked to identify major pleasant and stressful events that had occurred in the past 12 months. The most frequently described pleasant events related to children's behavior, school activities, and interactions with professionals and friends. Frequently described problem areas included children's behavior, professionals/services, and difficulty with school. The impact of these pleasant and stressful events was examined with respect to caregivers' perceived well-being: (1) overall stress, (2) the ability to fulfill responsibilities, and (3) pleasure experienced in various life domains. Implications of the study findings for supporting family caregivers in their roles are discussed.
Family-Centered Practice with Single-Parent Families
Authors: Jung Marshall
Published: April 2013

Using case examples, the author identifies four major issues resulting from divorce or separation that these families must confront. The article concludes with six practice principles for helping practitioners in their work.
Receipt of Child Support by Working Single Women
Authors: Caputo Richard K.
Published: April 2013

Using logistic regression, the author found that sociodemographic factors, particularly race, education, and number of children/young adults, more than attitudinal factors, distinguished recipients of child support from nonrecipients among formerly married working mothers in 1988 and 1991. In 1991, for formerly married mothers, child-care affinity was the only attitudinal characteristic associated with the likelihood of receiving child support. Because of the small sample sizes, findings about never-married working mothers were more ambiguous. Policy and practice implications are discussed.
Taking Responsibility: An Insider View of Teen Motherhood
Authors: Rains Prue , Davies Linda , McKinnon Margaret
Published: April 2013

The issue of responsibility looms large in the public discourse about teen mothers, but it is also a central concern for teen mothers themselves. This article draws on exploratory interviews with teen mothers to contrast their insider with outsider views about what taking responsibility for the baby entails, to show the context in which their views make sense, and to argue that outsider views be revised to take into account these insider considerations. Outsiders recommend measures to hold fathers financially accountable for their children, to make teen mothers live with a parent, and to make teen mothers work rather than assistance from welfare. From the perspective of teen mothers, however, taking responsibility for the baby often means avoiding rather than seeking financial dependence on unreliable fathers of the baby, claiming rather than delegating their role as mothers, and staying on welfare rather than working at an unreliable job.

Strength and empowerment perspectives in clear accordance with social work values are presented as practice models.
Biofunctionalized nanofibrous membranes mimicking carnivorous plants
Authors: Homaeigohar Shahin , Disci-Zayed Duygu , Dai Tianhe , Elbahri Mady
Published: April 2013

A novel biofunctionalized nanofibrous membrane is developed through immobilization of protein ligands on the surface of nanofibers. The biofunctionalization not only enhances the membrane’s structural properties including mechanical and thermal ones but also makes the membrane capable to separate nanoparticles and biomolecules much smaller than the pore size from water efficiently. Upon contact with water, the conformational change of the protein immobilized leads to its swelling, thereby an enlarged functional surface area and a higher steric hindrance capturing the filtrates. In case of filtration of a plasmonic nanoparticle containing suspension, decoration of the membrane with the plasmonic nanoparticles forms a smart bionanocomposite biosensor for detection of protein denaturation.
Expanding catalytic applications of Pt-functionalized metal organic frameworks (Pt/ZIF-8): effects of calcination temperatures and metal loadings
Authors: He Zhong , Zhang Guangyu , Wu Zhiyi , Qian Zheng , Wang Xianqin
Published: April 2013

ZIF-8 with and without Pt loadings (0·4 and 2·1 wt.%) were prepared at different calcination temperatures (300 and 400°C). The characterization from Brunauer–Emmett–Teller surface measurement and powder X-ray diffraction reveals that calcination temperatures and Pt loadings have a significant effect on the porosity and crystallinity of ZIF-8-based materials. ZIF-8 calcined at 300°C (ZIF8-300) has a surface area of more than 800 m2/g with excellent crystallinity, while ZIF-8 calcined at 400°C (ZIF8-400) only has a surface area of less than 100 m2/g with nearly amorphous structure; Pt loading reduces the surface area by blocking the micropores and lowers the overall Bragg peak intensity by the inclusion of guest Pt(NH3)4(NO3)2 molecules and/or the formation of Pt nanoparticles in the framework. The surface area and crystallinity decrease with the increase in Pt loadings. 2·1 wt.% Pt/ZIF8-300 has a surface area of 355 m2/g and thermal stability up to 500°C; this catalyst shows potential activities for partial oxidation of methanol because Pt nanoparticles (10 nm) are highly and uniformly distributed in ZIF-8 framework.
Contacts and foot and mouth disease transmission from wild to domestic bovines in Africa

Published: April 2013

Wildlife is a maintenance host for several significant livestock diseases. Interspecific pathogen transmission may occur in complex socio‐ecological systems at wild‐domestic interfaces that have so far been seldom studied. We investigated the relationship between the dynamics of foot and mouth disease (FMD) in vaccinated and unvaccinated cattle populations with respect to frequency of contacts with African buffalo at different buffalo‐cattle interfaces.

A total of 36 GPS collars were deployed on African buffalo (Syncerus caffer) and cattle (Bos taurus,Bos indicus) to assess contact patterns at the periphery of 3 protected areas in Zimbabwe. Simultaneously, a longitudinal survey of 300 cattle with five repeated sampling sessions on known individuals during 16 months was undertaken. Immunological assays (ELISAs), that allowed tracking the production of antibodies following infection or vaccination, were used to assess serological transitions (i.e., incidence and reversion) in the surveyed cattle. Variation in rates of serological transitions across seasons, sites and as a function of the frequency of contact with buffalo was analyzed using generalized linear mixed models.

The incidence in the cattle populations of FMD antibodies produced following infection varied among sites and as a function of contact rates with African buffalo. The incidence was higher for sites with higher contact rates between the two species. The serological incidence was also related to seasons, being higher during the dry or rainy seasons depending on sites. The reversion rate pattern was the opposite of this incidence rate pattern. Vaccination seemed partly efficient at the individual level, but it did not prevent the diffusion of FMD viruses from the wild reservoir host to the domestic cattle population. Furthermore, antibodies were detected in areas where cattle had not been vaccinated, suggesting that the virus may have spread without being detected in domestic populations.

Access to resources shared by buffalo and livestock, particularly water and grazing areas during the dry season, could partly explain the observed patterns of FMD transmission. We discuss how insights on ecological processes leading to wildlife‐livestock contacts may provide some innovative solutions to improve FMD management, including surveillance, prevention or control of buffalo‐borne outbreaks, by adopting strategies targeting risky areas and periods.
Reliability of conventional shade guides in teeth color determination

Published: April 2013

Background/Aim. Color matching in prosthodontic therapy is a very important
task because it influences the esthetic value of dental restorations. Visual
shade matching represents the most frequently applied method in clinical
practice. Instrumental measurements provide objective and quantified data in
color assessment of natural teeth and restorations. In instrumental shade
analysis, the goal is to achieve the smallest ?E value possible, indicating
the most accurate shade match. The aim of this study was to evaluate the
reliability of commercially available ceramic shade guides. Methods. VITA
Easyshade spectrophotometer (VITA, Germany) was used for instrumental color
determination. Utilizing this device, color samples of ten VITA Classical and
ten VITA 3D - Master shade guides were analyzed. Each color sample from all
shade guides was measured three times and the basic parameters of color
quality were examined: ?L, ?C, ?H, ?E, ?Elc. Based on these parameters
spectrophotometer marks the shade matching as good, fair or adjust. Results.
After performing 1,248 measurements of ceramic color samples, frequency of
evaluations adjust, fair and good were statistically significantly different
between VITA Classical and VITA 3D Master shade guides (p = 0.002). There
were 27.1% cases scored as adjust, 66.3% as fair and 6.7% as good. In VITA 3D
- Master shade guides 30.9% cases were evaluated as adjust, 66.4% as fair and
2.7% cases as good. Conclusion. Color samples from different shade guides,
produced by the same manufacturer, show variability in basic color
parameters, which once again proves the lack of precision and nonuniformity
of the conventional method.
Finite element analysis in defining the optimal shape and safety factor of retentive clasp arms of removable partial denture

Published: April 2013

Bacground/Aim. Retentive force of removable partial denture (RPD) directly
depends on elastic force of stretched retentive clasp arms (RCAs). During
deflection RCA must have even stress distribution. Safety factor is the
concept which can be applied in estimating durability and functionality of
RCAs. This study was based on analyzing properties of clasps designed by
conventional clasp wax profiles and defining the optimal shapes of RCAs for
stress distribution and safety factor aspects. Methods. Computer-aided-design
(CAD) models of RCAs with simulated properties of materials used for
fabrication of RPD cobalt-chromium-molybdenum (CoCrMo) alloy, commercially
pure titanium (CPTi) and polyacetale were analyzed. Results. The research
showed that geometrics of Rapidflex profiles from the BIOS concept are
defined for designing and modeling RCAs from CoCrMo alloys. I-Bar and
Bonihard clasps made from CPTi might have the same design as Co- CrMo clasp
only by safety factor aspect, but it is obvious that CPTi are much more
flexible, so their shape must be more massive. Polyacetale clasps should not
be fabricated by BIOS concept for CoCrMo alloy. A proof for that is the low
value of safety factor. Conclusion. The BIOS concept should be used only for
RCAs made of CoCrMo alloy and different wax profiles should be used for
fabricating clasps of other investigated materials. The contribution of this
study may be the improvement of present systems for defining the clasps
shapes made from CoCrMo alloys. The more significant application is
possibility of creating new concepts in defining shapes of RCA made from CPTi
and polyacetale.
Glycemic Control Associated With Secure Patient-Provider Messaging Within a Shared Electronic Medical Record
Authors: Harris Lynne T. , Koepsell Thomas D. , Haneuse Sebastien J. , Martin Diane P. , Ralston James D.
Published: April 2013

OBJECTIVE

To study differences in glycemic control and HbA1c testing associated with use of secure electronic patient-provider messaging. We hypothesized that messaging use would be associated with better glycemic control and a higher rate of adherence to HbA1c testing recommendations.

RESEARCH DESIGN AND METHODS

Retrospective observational study of secure messaging at Group Health, a large nonprofit health care system. Our analysis included adults with diabetes who had registered for access to a shared electronic medical record (SMR) between 2003 and 2006. We fit log-linear regression models, using generalized estimating equations, to estimate the adjusted rate ratio of meeting three indicators of glycemic control (HbA1c <7%, HbA1c <8%, and HbA1c >9%) and HbA1c testing adherence by level of previous messaging use. Multiple imputation and inverse probability weights were used to account for missing data.

RESULTS

During the study period, 6,301 adults with diabetes registered for access to the SMR. Of these individuals, 74% used messaging at least once during that time. Frequent use of messaging during the previous calendar quarter was associated with a higher rate of good glycemic control (HbA1c <7%: rate ratio, 1.26 [95% CI, 1.15–1.37]) and a higher rate testing adherence (1.20 [1.15–1.25]).

CONCLUSIONS

Among SMR users, recent and frequent messaging use was associated with better glycemic control and a higher rate of HbA1c testing adherence. These results suggest that secure messaging may facilitate important processes of care and help some patients to achieve or maintain adequate glycemic control.
Dichotomies for Lorentz spaces

Published: April 2013

Assume that L
p,q, $L^{p_1 ,q_1 } ,...,L^{p_n ,q_n } $ are Lorentz spaces. This article studies the question: what is the size of the set $E = \{ (f_1 ,...,f_n ) \in L^{p_{1,} q_1 } \times \cdots \times L^{p_n ,q_n } :f_1 \cdots f_n \in L^{p,q} \} $.

We prove the following dichotomy: either $E = L^{p_1 ,q_1 } \times \cdots \times L^{p_n ,q_n } $ or E is σ-porous in $L^{p_1 ,q_1 } \times \cdots \times L^{p_n ,q_n } $, provided 1/p ≠ 1/p
1 + … + 1/p
n. In general case we obtain that either $E = L^{p_1 ,q_1 } \times \cdots \times L^{p_n ,q_n } $ or E is meager. This is a generalization of the results for classical L
p spaces.

Published: April 2013

Different species of vector snails carry larval stages of different trematodes. Studies were performed to investigate different snail species and parthinate of trematodes carried by them, in some selected areas of Mymensingh Sadar, Mymensingh. Snails were collected by hand picking method and examined after crushing. Among 864 tested snails, it revealed the presence of six species of snails like Lymnaea auricularia 145 (16.8%), Lymnaea luteola 205 (23.7%), Indoplanorbis exustus 273 (31.6%), Vivipara spp. 164 (18.9%), Brotia spp. 35 (4.1%) and Pila spp. 42 (4.8%) in the study areas. Among them 5.8% L. luteola and 6.2% L. auricularia were infected with gymnacephalus cercariae. Again, 1.4% L. auricularia and 1.8% I. exustus were infected with echinostome cercaria. In this study, 1.8% Vivipara spp. and 2.6% I. exustus were positive for furcocercus cercaria. On the other hand, 1.8% Vivipara spp. was positive for xiphidocercus cercariae and 1.8% I. exustus was also positive for amphistome cercariae. One or more species of snails were found to harbor single or mixed types of cercariae such as gymnacepahlus, echinostome and furcocercous. Population densities of different species of snails were determined in per unit time which were statistically significant (p<0.01). More studies are needed to focus on the determination of different vector snails and cercariae carried by them throughout the Bangladesh especially from plain lands, hilly areas, alluvial lands and coastal areas during four conventional seasons.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14599 J.

This study deals with the investigation of water quality of the Buriganga river, Dhaka. For this purpose, samples were collected from five locations of the Buriganga river of Bangladesh during wet (monsoon) and dry (winter) season in 2011 to determine the spatial distribution and temporal variation of various water quality parameters. Water samples were collected from three different depths of river. The color was light brown in wet season and slightly black to black color in dry season. The water was found slightly acidic to slightly alkaline (6.6-7.5). Water temperature ranged from 18.2°C (dry) to 27.04°C (wet). The river was found to be highly turbid both in dry and wet season. Biochemical Oxygen Demand (BOD), Electric Conductivity (EC) and Total Dissolved Solids (TDS) were found higher in the dry season compared to that of wet season, while Dissolved Oxygen (DO) was found higher in wet season. The mean values of parameters were EC: wet- 1685 ?s/cm, dry-2250 ?s/cm; DO: wet- 4.9 mg/L, dry-3.7 mg/L; BOD: wet- 26.4 mg/L, dry- 33.4 mg/L; TDS: wet-238 mg/L, dry- 579 mg/L; transparency: wet- 24.6 cm, dry- 22.8 cm.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14600 J.

Published: April 2013

Combining ability and gene action for different root characters were studied in seven genotypes of spring wheat and their 21 F1s obtained from a diallel crosses. The experiment was conducted with 45 days aged plant in poly bags at the field laboratory of Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh. The parent Kheri was the best general combiner for different root characters. The crosses Sebia × SA-92, Sebia × HT-7 and SA-92 × Kheri showed positive and significant SCA effects for root length.VrWr graph analysis showed that dry weight of root and shoot root ratio indicates epistasis. Whereas root length and dry weight of shoot showed over dominance. The crosses with SCA significant effects for root characters may be used in hybrid development in spring wheat.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14605 J. Environ.

Published: April 2013

Bangladesh is one of the most disaster prone countries in the world and is a victim of frequent natural calamities like tropical cyclones, tornadoes, floods, storm surges and droughts. Sea surface temperature (SST) plays a vital role in determining ocean-atmosphere interaction. In this study we focused on understanding the behavior of SST anomaly prevailed in the region of Bay of Bengal mainly to assume the surface temperature signature for cyclone occurrence. For this study, the observed SST anomaly data were derived from NOAA Coast-watch using a combination of global and regional algorithms. The SST anomaly maps were produced using SAGA-GIS software where the SST lines were fixed at the mean of 30 years data. The AVHRR SST was compared with the climatological SST for the region of Bay of Bengal in 2010. The monthly SST anomaly for 2010 showed average departure of 0.7°C for all the months except June and October. It was found that the anomaly increases about 2°C at the end of September, and in October the basin bears no significant anomaly.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14797 J. Environ.

Published: April 2013

A field experiment was conducted at the farmers field of Livelihood Improvement of Farming Community in Haor Area through System Approach Project site Purbo Tethulia, Mohangonj, Netrakona during the Rabi Season of 2011-2012 to shorten the field duration of potato through seed pre-sprouting technique and to find out the suitable potato variety for cultivation in Dingaputa haor area without affecting the cultivation period of boro rice. Diamont and one local variety Challisha were taken for the study. Pre-sprouting duration of Diamont was 10, 20, 30 and 40 days with un-sprouted Diamont and Challisha. In the study unsprouted Diamont produced significantly the highest yield (25.28 tha-1) followed by 20.01, 13.46, 13.31, 12.74 and 11.54 tha-1 of 10, 20, 30, 40 days pre-spouted Diamont and un-sprouted Challisha, respectively. The lowest field duration of the crop was 41 days of 30 and 40 days pre-spouted Diamont. The highest gross margin of Tk.165960 ha-1 was observed from the unsprouted Diamont potato against the variable cost of Tk.137400 ha-1 incurred. The performance of Challisha was also appreciated by the farmers for its quality and low cost of production. Unsprouted Diamont potato also ranked the top most position in terms of benefit cost ratio of 2.21.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14815 J. Environ.

Published: April 2013

A pot experiment was carried at Patuakhali Science and Technology University to study the performance of some BARI wheat varieties under the coastal area of Patuakhali. Four wheat varieties viz. BARI ghom-23, BARI ghom-24, BARI ghom-25 and BARI ghom-26 were planted in the field to evaluate their comparative performance in respect of germination percentage, growth, yield and yield attributing characters. Among the four varieties, BARI ghom-26 showed superior performance irrespective of all parameters studied except total dry matter content (TDM) and yield reduction percentage. Among the BARI varieties, BARI ghom-26 produced greater germination (61.00%) at 13 days judge against to other varieties. The taller plant (47.91 cm), higher LAI (1.84), maximum TDM (17.37 g plant-1) and effective tillers hill-1 (18.08) were also obtained with the similar variety. BARI ghom-26 was also most effective to produce the maximum grains spike-1 (38.52), higher weight of 1000-grains (49.38 g), higher grain (3.35 t ha-1) and straw (8.50 g plant-1) yield and greater HI (4.03%). So, the variety BARI ghom-26 produced the outstanding superiority among the varieties.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14816 J. Environ. Sci. & Natural Resources, 5(2): 209-212 2012

Published: April 2013

The study was conducted to investigate the effects of solid waste and industrial effluents on the water quality of Turag River. Both the upstream and downstream sampled water from the selected points were analyzed for color, odor, pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), copper (Cu), cadmium (Cd), iron (Fe), lead (Pb) and zinc (Zn) concentrations. Results of the study showed that the color of water was light to dark black and emitted noxious smell due to the industrial effluents. The upstream water was slightly alkaline with comparatively high DO content while low concentration of other parameters. The water after the solid waste and effluents received points as well as middle and downstream points was slightly alkaline with higher levels of other parameters when compared with upstream point. The minimum and maximum values of pH, EC, TDS, DO and BOD were 7.24-7.61, 425-2277 ?S/cm, 239-1349 ppm, 1.22-3.66 ppm and -2.44-0.86 ppm, respectively. The continuous dumping of waste materials resulted in a marked increase in the concentration of metals in the river water varied in the order of Fe > Zn > Pb > Cu > Cd. The study concluded that the downstream water in the river was almost polluted and unsuitable for human consumption and aquaculture purposes.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14817 J.

Published: April 2013

This study is designed to explore the local people survival strategies and assesses variation in peoples ability to cope with flood and riverbank erosion of two char land (Mid-channel Island) villages of Bangladesh. The data were collected by the application of social survey, key informant interview, focus group discussions and field observation. Most of the people of the char land villages were affected by both flood and river erosion. The result of the study showed that devastating river erosion occurred in Shushua char as compared with Degreer char in 2010 and people tried to adapt with adverse situation by their own techniques. People of both the chars were experienced flooding more than two months in the same year. Households ability to adapt with flood and river erosion depends on peoples socioeconomic and environmental conditions, such as education, income and occupation. Though, flood and river erosion cause the loss of lives and properties, peoples indigenous coping techniques could significantly reduced their vulnerability without outside assistance. Effective early warning system, integrate local coping practice with modern technology and improve socioeconomic condition in a sustainable way are necessary to reduce the losses from flood and riverbank erosion.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14827 J.

Published: April 2013

The fecundity of 100 gravid female fishes of Jat puti, Puntius sophore, was collected from the experimental ponds of the Field Laboratory Complex, Faculty of Fisheries, Bangladesh Agricultural University (BAU), Mymensingh was estimated during the period from June to August 2011. Collected samples were clustered month-wise: group A (collected in June), group B (collected in July) and group C (collected in August). The estimated fecundity ranged of 7951 to 17670; 8135 to 23053 and 12461 to 15105 eggs and the mean gonadosomatic index (GSI) of 23.44 ± 2.50; 30.47 ± 4.52 and 28.43 ± 2.99 was estimated for the fish group of A, B, and C, respectively. The relationship between fecundity and total length was linear and it was expressed as: Ln F= 1634 ln TL-1972; Ln F= 119405 ln TL-273.53 and Ln F= 1831.6 ln TL+ 825.31 in group A, B, and C, respectively. The regression equation between body weight and total length was linear and it was expressed as: Ln W= 2.2128 ln TL- 0.7048; Ln W= 2.0207 ln TL+ 0.3493 and Ln W= 1.4438 ln TL+ 5.5694, in group A, B, and C, respectively. The regression equation between body weight and fecundity was linear and it was expressed as: F= 656.84 W+199.96, F= 438.16 W+2470, F= 1116.1 W-3433.5, in group A, B, and C, respectively. The fecundity was highly correlated with the total length, and body weight and P. sophore may be a medium fecund fish.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14833 J. Environ.

Formes et usages du discours historiographique chez les grammairiens français
Authors: Fournier Jean-Marie , Raby Valérie
Published: April 2013

ABSTRACT: In this paper, we examine the range of the perspectives taken on the past of grammatical theory (retrospective horizon [ horizon de rétrospection]). This issue is addressed through a typology of discursive representations which belong to a period extending from the 16th century to the beginning of the 19th. We distinguish three major discursive representations. First, simple mentions, allusive or personal, of previous grammarians, as they can be encountered in grammars. Secondly, historiographical compilations, which fall within the genre of bibliothèques. Thirdly, historiographical essays properly speaking, which, at the end of the 18th century, take the shape of tableaux des progrès (or «sketches of a picture of progress»). These various ways of referring to the past point to a new awareness of the historicity of linguistic theories, which is seen to emerge in the second half of the 18th century.
L’histoire de la linguistique, un élément d’une culture linguistique nationale
Authors: Archaimbault Sylvie
Published: April 2013

RÉSUMÉ: Dans cet article nous réfléchissons sur la propension, assez partagée chez les grammairiens et linguistes russes, à monumentaliser la langue russe. Dans cette vision d’un patrimoine partagé par des locuteurs idéaux, dont la persistance dans la durée ne manque pas de frapper l’observateur, la vénération dont certaines grandes figures sont l’objet vient en bonne place. Le cas de Mixail Lomonosov est emblématique de la construction d’une tradition linguistique qui tend à se confondre avec une tradition nationale.
De Brosses, Jakobson et l'ontogenèse phonologique
Authors: Nobile Luca
Published: April 2013

The idea of a fixed order in the appearance of phonemes in child language is very ancient. We already find it in Plutarch. However, in the middle of the 18th century, Buffon still only knows three steps of this progression. Jakobson criticizes Buffon's method in the beginning of his famous essay on the topic. Buffon's classification is used by De Brosses in a lost essay of 1753 : Beauzée gives evidence of the contents of this essay in his article «Langue» of the Encyclopédie.

But in the Traité of 1765, the president, resorting to some new empirical observations, proposes a more articulated classification. This classification anticipates in some points the one proposed by Jakobson, both in its descriptive results and in the intuition of the structural rule. In 1802 Thiébault proposes a simplified version of this classification. Today De Brosses's «primitive linguistics» deserves to be analyzed again in the light of cognitive linguistics.
Saussure, la syllabe et le phonème
Authors: Leoni Federico Albano
Published: April 2013

Cet article analyse les réflexions de Saussure sur la phonologie. La lecture des textes (CLG, sources et autres écrits) montrent que Saussure accordait moins d’importance aux segments phoniques en soi qu’à leurs relations dans la chaîne, surtout en termes d’alternance entre processus d’ouverture et de fermeture, fondamentaux pour la définition de la syllabe et correspondant à des mécanismes universels. Il apparaît en outre que l’opinion courante, soutenue essentiellement par Jakobson, selon laquelle une conception du phonème moderne serait présente chez Saussure, fût-ce de manière implicite, est infondée.
Les langues des Indes orientales entre Renaissance et Âge classique
Authors: Demonet-Launay Marie-Luce , Uetani T.
Published: April 2013

Les langues des Indes orientales ont été des instruments au service des trois mobiles de la découverte de nouvelles terres : la conquête, le commerce et la conversion. Les routes des langues coïncident avec celles des épices et de la soie, surtout dans la première moitié du 16e s. où une multitude d’idiomes auront été appris dans la hâte de l’installation des forteresses, des comptoirs et des églises, avant de susciter un intérêt scientifique majeur (pour le chinois et le japonais en particulier). Ces langues pérégrines ouvrent les savoirs occidentaux à une colonisation également linguistique. Elles alimentent un certain goût de la merveille qui se transformera, au cours du 17e s., en exotisme littéraire. À une époque où les protestants conduisent leurs propres missions, jésuites et ordres mendiants rivalisent de compétence linguistique. En France, Guillaume Postel, Blaise de Vigenère et Claude Duret donnent à lire trois traitements de ces nouveautés : l’annexion à un idéal messianique, l’intérêt cognitif pour une écriture universelle et la réprobation à l’encontre d’idéogrammes monstrueusement païens.
