Feeding difficulties in children with cerebral palsy

Feeding difficulties are common in children with cerebral palsy and have an effect on growth, nutritional state, general health, social interaction and behaviour and developmental outcomes. Many factors have an effect on feeding ability. Identification of these factors and amelioration of their impact on feeding difficulties is essential to promote adequate growth and nutrition. Appropriate assessment and management is best achieved by a multiprofessional team skilled in the care of children with cerebral palsy and feeding impairments. Feeding difficulties must be considered within the wider context of family and social circumstance.
I NTERNAL S ECURITY ON AN IDS BASED ON A GENTS

An Intrusion Detection System (IDS) can monitor different events that may occur in a determined network or host, and which affect any network security service (confidentiality, integrity, availability). Because of this, an IDS must be flexible and it must detect and trace each alert without affecting the system ́s performance. On the other hand, agents ina MultiAgent system have inherent security problems due to their mobility; that’s why we propose some techniques in order to provide internal security for the agents belonging to the system. The deployed IDS works with a multiagent platform and each component inside the infrastructure is verified using security techniques in order to provide integrity. Likewise, the agents can specialize in order to carry out specific jobs, for example monitoring TCP, UDP traffic, etc. The IDS can work without interfering in the system's performance. In this article we present a hierarchical IDS deployment with internal security on a multiagent system, using a platform named BESA with its processes, functions and results.
The Voices of High School Dropouts: Implications for Research and Practice.

Dr. Alice Fisher Sam Houston State University PO Box 2119 Huntsville, Texas 77341 Edu_axf@shsu.edu 936.294. 1165 Originally developed in 1942, the General Educational Development (GED) exam was designed to help veterans who had left high school before graduation in order to join the armed services. This certificate allowed them to pursue college degrees without having to go back to high school (Brown, 2000). Over the years, people from all walks of life have earned the GED diploma, among them United States Senator Ben Nighthorse Campbell of Colorado; comedian Bill Cosby; actor Michael J Fox; and musicians Waylon Jennings and John Michael Montgomery.
Cytotoxicity of diatom-derived oxylipins in organisms belonging to different phyla

SUMMARY The cytotoxicity of several saturated and unsaturated marine diatom-derived aldehydes and an oxo-acid have been screened in vitro and in vivo against different organisms, such as bacteria, algae, fungi, echinoderms, molluscs and crustaceans. Conjugated unsaturated aldehydes like 2E,4E-decadienal, 2E,4E-octadienal, 5E,7E-9-oxo-nonadienoic acid and 2E-decenal were active against bacteria and fungi and showed weak algicidal activity. By contrast, the saturated aldehyde decanal and the non-conjugated aldehyde 4Z-decenal had either low or no significant biological activity. In assays with oyster haemocytes, 2E,4E-decadienal exhibited a dose-dependent inhibition of cytoskeleton organisation, rate of phagocytosis and oxidative burst and a dose-dependent promotion of apoptosis. A maternal diatom diet that was rich in unsaturated aldehydes induced arrest of cell division and apoptotic cell degradation in copepod embryos and larvae, respectively. This wide spectrum of physiological pathologies reflects the potent cell toxicity of diatom-derived oxylipins, in relation to their non-specific chemical reactivity towards nucleophilic biomolecules. The cytotoxic activity is conserved across six phyla, from bacteria to crustaceans. Deregulation of cell homeostasis is supposed to induce the elimination of damaged cells through apoptosis. However, efficient protection mechanisms possibly exist in unicellular organisms. Experiments with a genetically modified yeast species exhibiting elevated membrane and/or cell wall permeability suggest that this protection can be related to the inability of the oxylipin compounds to enter the cell.
Employment outsourcing in information systems

growing trend. I N recent years, information systems (IS) outsourcing has become so pervasive it can no longer be ignored. An important question is why firms choose to outsource IS work. This question has been considered from a number of perspectives. Lacity and Hirschheim [14], for example, showed how the dynamics of internal politics led to IS outsourcing. Loh and Venkatraman [15] suggested that the outsourcing behavior of a prominent blue-chip company, such as Eastman Kodak, can lead to imitative behavior throughout the IS community. In contrast, our study examines the reasons for IS outsourcing from a somewhat different perspective----that of labor market economics. From this perspective, outsourcing is a result of how firms respond to the costs and benefits of employment arrangements with their IS workers. In the classic economic view of labor markets, workers move freely and frequently between jobs to take advantage of better employment opportunities. According to Doeringer and Piore [8], the traditional long-term employment arrangement replaced the open labor market because it afforded principals (employers) greater control and influence over agents (their employees). More recently, however, firms have been moving away from the traditional, long-term employment arrangement (insourcing) to relatively shorter-term, market-mediated arrangements (outsourcing). Outsourcing reflects the increasing trend toward “taking the workers back out” [19], in which organizations alter the work relationship with their employees by reducing the duration of employment and their degree of administrative control over workers. In IS outsourcing, taking the workers back out can occur in many ways. A firm can either contract directly with an IS professional for his or her services or contract indirectly with an employee leasing company, a consulting firm, or an IS service provider. Such practices can benefit both the firm and the IS worker. Although the Eastman Kodak outsourcing arrangement represents total IS outsourcing and has become a popular practice in industry, firms can also choose to selectively outsource for particular IS skills or jobs. But why do firms choose to selectively or completely outsource IS? From a labor market perspective, outsourcing is the response of firms to the costs and disadvantages of the traditional permanent work arrangement that arise from dynamic changes in technology and the environment. Due to the increasingly rapid evolution of information technology (IT), IS work is characterized by skills deterioration and specific skills shortages [16, 25]. Thus, a firm’s ability to find and acquire the necessary IS skills is paramount. Under these circumstances, relying on retraining a permanent work force may be cost prohibitive. In addition, because IT evolves so rapidly, by the time a firm invests in and trains its IS staff on a certain technology, that technology may be obsolete. There are indications that firms face increasing turbulence in the environment. As firms become inteEmployment Outsourcing
A route navigation system with a new revised shortest path routing algorithm and its performance evaluation

This paper presents a route navigation system with a new revised shortest path routing algorithm for solving road traffic problems. The system can avoid selecting no left (right) turns, one-way roads, and congested roads when it determines the shortest paths from source to destination. Also, the new revised routing algorithm is compared numerically with existing algorithms such as the Dijkstra algorithm and the A* algorithm. We choose a road network containing 4000 nodes which have 200 no left turn situations and find in particular that the road traffic problem of a 4000-node traffic network can be solved within only 0.651 seconds on average. The prototype system was built and some extra functions were added so that its benefits not only offer the shortest path but also provide information and security services for drivers.
Appearance based processes for visual navigation

This paper describes the use of appearance based vision for defining visual processes for navigation. A visual processes which transform images to commands and events. A family of visual processes are defined by associating the appearance of a scene from a given viewpoint with the simple trajectories. Appearance is captured as a set of low-resolution images. Energy normalised cross correlation is used to maintain heading, to estimated confidence and to servo control a robot vehicle while following a path. Experimental results are presented which compare results with a single camera, a pair of parallel cameras and a pair of divergent cameras. The most accurate (and robust) navigation is found with a pair of cameras which are slightly divergent.
Synthesis and Evaluation of α-Synuclein ( 636 )

Parkinson's disease is a common neurodegenerative disorder characterized by tremors and motors deficits, caused by the death of dopaminergic neurons and the resulting dopamine depletion in the brain. Examination of the substantia nigra of the brains of Parkinson's patients reveals abnormal intraneuronal deposition of fibrillar aggregates of the protein α-synuclein. While Parkinson's disease is generally idiopathic in origin, several mutations in α-synuclein have been shown to increase the likelihood of the disease. This further implicates α-synuclein in the pathogenesis of Parkinson's disease. This report focuses on wild type α-synuclein. A 31-residue peptide corresponding to residues 6-36 of the N-terminus of a-synuclein was synthesized, purified, and its conformation examined using circular dichroism spectroscopy. The peptide showed conformational behavior that is similar to what has been found for this region in the full-length protein. Thus, the peptide can be used as a model system for the N-terminal region of α-synuclein. In future work, this peptide model and its A30P mutant counterpart can be compared to characterize the role of this mutation in Parkinson's disease.
Perspectives on preparedness for a death among bereaved persons.

OBJECTIVE To present opinions of recently bereaved persons regarding how they could have been made to feel more prepared for the death of a loved one. METHODS Cross-sectional descriptive study that uses information from a longitudinal study. A face-to-face interview was administered to 122 recently bereaved persons and participants were asked to provide opinions and to describe whether health professionals, family/friends, or themselves could have helped them to feel more prepared for the death. RESULTS Of the total sample of 122, 31 (25%) reported that doctors or health professionals could have done something more to help make them feel better prepared for the death of their loved-one. Six subjects (4.9%) indicated family/friends, and 16 (13.1%) stated that they themselves could have done something more to help prepare for the death of their loved-one. Common themes were: the physicians' lack of communication regarding the prognosis and imminence of death, family survivors' concerns about the medical care provided, regrets engendered by their own denial of the patient's imminent death, not managing the illness in a manner consistent with the patient's impending death, and lost opportunities for closure in family matters, both financial and interpersonal. DISCUSSION Findings from this study can be used to enhance understanding of bereaved persons' views about health professionals' current practices for bereaved individuals, as well as the role of the family and the bereaved persons themselves in potentially effecting preparedness for the death of a loved one.
Growth characteristics of ameloblastoma involving the inferior alveolar nerve: a clinical and histopathologic study.

OBJECTIVE Growth characteristics of ameloblastomas involving the inferior alveolar nerve were examined to determine the most appropriate surgical management of the nerve at the time of the surgical procedure. STUDY DESIGN Clinical and histopathologic examinations were performed on 22 resected mandibles in which the inferior alveolar nerve was lying adjacent to, or contained within, the tumor. RESULTS Patterns of tumor involvement of the nerve bundle were evaluated with respect to the presence of bone (11 patients) or connective tissue wall (7 patients) between the tumor and the nerve bundle, and tumor infiltration of perineural connective tissue (4 patients). Neither invasion into the nerve sheath nor invasion into the nerve itself by the ameloblastoma was detected. Tumor infiltration of the tissue surrounding the nerve was identified for the multicystic and solid types but not for the unicystic type. Presence of bone or connective tissue wall between the tumor and the nerve bundle was dominant in the unicystic and plexiform ameloblastomas, whereas tumor infiltration of the perineural tissue was frequently observed in ameloblastomas with the follicular pattern. CONCLUSION The preservation of the inferior alveolar nerve may be possible in the management of the unicystic type of ameloblastoma. However, a more radical approach is necessary for treatment of multicystic or solid tumors, especially those exhibiting a follicular pattern.
The role of the Internet in the globalisation of small to medium-sized enterprises in Ukraine

The development of the small business sector in Ukraine is believed to be central to economic reforms and to the creation of wealth and employment (Isakova, 1997). Given the inherent instability and general weakness of the Ukrainian economy, there have been many internal and external obstacles to the development of small enterprises in a variety of business sectors. However, the recent growth and development of the Internet as a vehicle for business transformation has provided opportunities for small to medium-sized enterprises (SMEs) in Ukraine to enter global markets. The extent to which this is the case for Ukraine and similar developing economies is an emerging research issue, given that various studies have already identified tangible benefits for the growth of SMEs in developed economies (e.g. McWilliams, 1995; Daniel & Myers, 2000; Warren, 2000). This paper looks at the development of SMEs in Ukraine and outlines the factors that have affected their growth. The paper then focuses on the role of the Internet in the globalisation of SMEs, and considers the opportunities and potential limitations created by the Internet. This is then related to how the Internet can transform SMEs specifically in Ukraine, thereby addressing some of the current obstacles to their development. Examples of Ukrainian SMEs using Internet globalisation strategies are provided, and the opportunity for further research in this area is discussed.
Reduced antiplatelet therapy after drug‐eluting stenting: Multicenter janus flex carbostent implantation with short dual antiplatelet treatment for 2 or 6 months—matrix study

Objectives: The Multicentre registry with Antiplatelet TReatment two–sIX months (MATRIX) evaluated safety and efficacy at 12‐month follow‐up of Janus Flex stenting with 2‐ or 6‐month dual antiplatelet therapy (DAT) period. Background: There are no data of Janus Flex stent (Carbostent and Implantable Devices—CID, Saluggia, Italy), a polymer‐free, tacrolimus‐eluting coronary stent, followed by short‐term DAT, in daily practice. Methods: Patients were prospectively enrolled at 12 high‐volume procedures centres. After stenting, four sites prescribed 2‐month DAT, eight sites 6‐month DAT. Major adverse cardiac events (MACE) and stent thrombosis (ST) rate was evaluated at 12‐month follow‐up, for entire population, as well as for 2‐ and 6‐month DAT groups, distinctly. MACE included cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR). Results: From March 2007 to June 2008, 572 patients (mean age 64.91 ± 11 years, 77.45% males) were enrolled. After successful stenting, 12‐month follow‐up showed a 12.74% MACE occurrence (cardiac death 0.98%; MI 3.13%; TLR 8.62%), with good Janus Flex safety profile confirmed by only two (0.39%) ST. After adjustment for potential confounding, no significant differences were noted at 12‐month follow‐up among 2‐ or 6‐month DAT groups (MACE—8.99% versus 12.47%, P = 0.16; cardiac death—0.54% versus 1.14%, P = 0.52; MI—2.38% versus 2.71%, P = 0.83; TLR—5.66% versus 10.60%, P = 0.20; ST—0% versus 0.55%, P = 0.99). At multivariable analysis, DAT time duration was not an independent risk factor for adverse events (adjusted HR 0.47, 95% confidence interval 0.16–1.35, P = 0.16). Conclusions: Janus Flex coronary stenting, followed by short DAT, is safe and feasible, without differences between 2‐ and 6‐month DAT groups. A randomized trial confirming these encouraging data is needed. © 2011 Wiley Periodicals, Inc.
Multiple Agents Moving Target Search

We introduce a nonparametric approach to multiscale analysis of document corpora using a hierarchical matrix analysis framework called diffusion wavelets. In contrast to eigenvector methods, diffusion wavelets construct multiscale basis functions. In this framework, a hierarchy is automatically constructed by an iterative series of dilation and orthogonalization steps beginning with an initial set of orthogonal basis functions, such as the unitvector bases. Each set of basis functions at a given level is constructed from the bases at the lower level by dilation using the dyadic powers of a diffusion operator. A novel aspect of our work is that the diffusion analysis is conducted on the space of variables (words), instead of instances (documents). This approach can automatically and efficiently determine the number of levels of the topical hierarchy, as well as the topics at each level. Multiscale analysis of document corpora is achieved by using the projections of the documents onto the spaces spanned by basis functions at different levels. Further, when the input term-term matrix is a "local" diffusion operator, the algorithm runs in time approximately linear in the number of non-zero elements of the matrix. The approach is illustrated on various data sets including NIPS conference papers, 20 Newsgroups and TDT2 data.
Phylogenetic relationships within the family potyviridae: wheat streak mosaic virus and brome streak mosaic virus are not members of the genus rymovirus.

ABSTRACT The complete nucleotide sequence of wheat streak mosaic virus (WSMV) has been determined based on complementary DNA clones derived from the 9,384-nucleotide (nt) RNA of the virus. The genome of WSMV has a 130-nt 5' leader and 149-nt 3'-untranslated region and is polyadenylated at the 3' end. WSMV RNA encodes a single polyprotein of 3,035 amino acid residues and has a deduced genome organization typical for a member of the family Potyviridae (5'-P1/HC-Pro/P3/6K1/CI/6K2/VPg-NIa/NIb/CP-3'). Because WSMV shares with ryegrass mosaic virus (RGMV) the biological property of transmission by eriophyid mites, WSMV has been assigned to the genus Rymovirus, of which RGMV is the type species. Phylogenetic analyses were conducted with complete polyprotein or NIb protein sequences of 11 members of the family Potyviridae, including viruses of monocots or dicots and viruses transmitted by aphids, whiteflies, and mites. WSMV and the monocot-infecting, mite-transmitted brome streak mosaic virus (BrSMV) are sister taxa and share a most recent common ancestor with the whitefly-transmitted sweet potato mild mottle virus, the type species of the proposed genus "Ipomovirus. " In contrast, RGMV shares a most recent common ancestor with aphid-transmitted species of the genus Potyvirus. These results indicate that WSMV and BrSMV should be classified within a new genus of the family Potyviridae and should not be considered species of the genus Rymovirus.
New functions of protein kinase Gcn2 in yeast and mammals

The classical role of the conserved Gcn2 kinase of yeast and mammals is to activate the translation of the transcription factors Gcn4 in yeast and activating transcription factor 4 in mammals by phosphorylating the eukaryotic translation initiation factor 2α. Gcn2 is activated by uncharged tRNAs in response to amino acid starvation and this regulatory system is important for tolerance to nutrient deprivation and other stresses and for development, differentiation, and normal function of mammalian organs. In the past few years, the classical Gcn2 pathway has been shown to modulate life span, tumor cell survival, and immune responses. In addition, Gcn2 modulates translation of novel mRNAs such as those of an unknown regulator of leucine transport and of sulfiredoxin SRX1 in yeast (activation of translation) and of inducible nitric oxide synthase, ErBb2, HIF1a, and 5′‐terminal oligopyrimidine tract mRNAs in mammals (inhibition of translation). Finally, Gcn2 directly phosphorylates novel proteins such as methionyl‐tRNA synthetase in mammals, and this triggers a pathway for DNA repair. These findings anticipate many expanding roles of Gcn2 in the future, with relevance for stress responses and human disease. © 2012 IUBMB IUBMB Life, 64(12): 971–974, 2012
Novel Unipolar Orthogonal Frequency Division Multiplexing (U-OFDM) for Optical Wireless

A novel modulation technique coined U-OFDM is proposed. U-OFDM uses different time sample states and an innovative rearrangement of the Orthogonal Frequency Division Multiplexing (OFDM) frame which allow for the creation of unipolar OFDM signals required for Optical Wireless Communication (OWC) with Light Emitting Diodes (LEDs). In comparison to similar techniques like DC-biased Optical OFDM (DCO-OFDM) and Asymmetrically Clipped Optical OFDM (ACO-OFDM), U-OFDM is both optically and electrically more power efficient in an Additive White Gaussian Noise (AWGN) channel, which is prevalent in an optical wireless system.
The Role of Self-Views in College Adjustment

The transition to college presents a host of stressors for students to navigate in the novel environment. Previous research has shown that the transition to college and adaptation to new demands can be highly distressing for students. College adjustment has been shown to predict retention rates and uptake of risk behaviors such as alcohol use. It is likely that some students may be at greater risk for maladjustment based on their ability to adapt to the college environment. Thus, the current study examined how individual differences in self-views relate to college adjustment. Ninety-one participants (75 females and 16 males) completed measures of self-concept clarity, self-esteem, selfacceptance, and college adjustment. College adjustment was significantly correlated with self-concept clarity (r = .29, p = .01), self-esteem (r = .39, p = .00) and self-acceptance (r = .36, p = .00). These results have important implications for university programs that focus on facilitating the transition to college, espousing the need for interventions that address promotion of acceptance of self and life events.
