Two historical strands in studying visual direction1

How we see the direction of an object has been discussed since the time of Aristotle. Despite this early beginning, there are two strands of conflicting ideas on visual direction that remain to this day. The first strand is based on observation or phenomenology and generated the idea that the midpoint between the two eyes is the reference point for visual direction. The second strand is related to geometry or optics and generated the idea that the reference point is an eye. To discuss this issue, we focus on visual directions of stimuli that stimulate both foveas. The observational strand has provided ample evidence to support their idea that the midpoint between the eyes is the reference point, yet the idea that the reference point resides in an eye still persists. We examine how the two strands have evolved since antiquity and speculate as to why the second strand persists. We then offer an intuitive explanation for the idea generated by the first strand in order to counter the persistence of the idea generated by the second.
The Personality of Judges as a Factor in the Validity of Their Judgments of Extraversion‐Introversion

The questionnaire responses of nominated extraverts and introverts on the extraversion and neuroticism scales of the Eysenck Personality Inventory were studied, in conjunction with the E and N scores of the judges, and their intelligence test scores. High validity of choice was observed, but no relationship found between personality or intelligence of the judges, and the excellence of their judgments.
A relative impact ranking of political studies in Ireland

Against a background of the Irish government’s concerns with Key Performance Indicators (KPIs) and the British government’s wishes for a more quantitative Research Assessment Exercise (RAE), our study conducts a relative impact assessment of the study of politics, government, political science, and international relations in Ireland. Impact is measured as citations from the publications of permanent staff in eight Irish politics departments, based on data compiled in April 2008 from two leading academic indexes – ISI’s Web of Science and Scopus – as well as the now popular Google Scholar. We discuss some of the criticisms that naturally arise in a study of this nature. Then, following similar exercises in other disciplines (e.g. economics), we use the impact measures to compare and rank individual scholars as well as departments. We also explore the extent to which the choice of different indexes, and different measures, influences the results that we obtain. While there are differences, in particular between indexes based purely on articles and those that access books and other material, the results from the different indexes are strongly correlated.
Subjective experiences of 24 patients dramatically recovering from stroke.

BACKGROUND There are no reports describing patients' perception of having a stroke and then dramatically recovering. SUMMARY OF REPORT We interviewed 24 patients randomized at our center to intravenous tissue plasminogen activator or placebo in an ongoing multicenter blinded prospective study. These patients demonstrated at least 50% improvement or an absolute improvement of 5 points on the National Institutes of Health Stroke Scale during the first 24 hours after treatment, with 7 patients returning completely to normal. Twelve of 24 of the strokes involved the right middle cerebral artery, 2 of 24 the right posterior cerebral artery, 8 of 24 the left middle cerebral artery, and 2 of 24 the basilar artery territory. CT scans at 24 hours or 1 week showed infarction in 19 of 24. Most patients (19 of 24) could clearly recall the exact circumstances involving the onset of their stroke, but only 12 of 24 were aware of the magnitude of their neurological deficit (7 of 14 right hemisphere and 4 of 8 left hemisphere patients). Only 6 of 24 were aware of their improvement when it occurred (3 of 14 right hemisphere and 2 of 8 left hemisphere patients). Five of 24 remembered positive phenomena such as warmth or tingling during their recovery, and only 2 patients demonstrated euphoria. Most patients seemed peculiarly unaware or blasé about their deficit and improvement. CONCLUSIONS Most patients with acute stroke are not aware of the severity of their problem, and recovering patients do not remember important events during the next 24 hours. This occurs with either right or left hemisphere lesions and may have a significant impact on early stroke recognition.
Neuromuscular transmission at newly formed neuromuscular junctions in the regenerating soleus muscle of the rat.

1. A study of neuromuscular function in regenerating skeletal muscle fibres in the rat soleus muscle has been made. The muscle fibres were damaged in vivo by the injection of the myotoxic venom component notexin, and then allowed to regenerate spontaneously. 2. Regenerating muscle fibres generated action potentials and contracted following direct intracellular stimulation as early as 4 days after the injection of notexin. 3. Miniature endplate potentials (MEPPs) were recorded at a minority of synapses at 3 days, and from all synapses by 5 days. The mean amplitude of MEPPs in a given fibre was directly proportional to muscle fibre input resistance. 4. Spontaneous transmitter release in the regenerating fibres was relatively insensitive to changes in [K+]0 but the effect of Ruthenium Red on spontaneous release was similar in the regenerating and control muscle fibres. 5. Functional innervation, defined as the ability to generate an indirect action potential, was restored in 97% of fibres by 10 days. The generation of an action potential was always associated with a twitch of the muscle fibre. Those fibres that were unable to generate an action potential usually exhibited a low membrane potential (ca ‐50 mV). These fibres could generate action potentials if they were hyperpolarized using an intracellular current‐passing microelectrode. 6. The quantal content of endplate potentials (EPPs) was estimated from the mean EPP and mean MEPP amplitudes in cut muscle fibre preparations. These estimates suggested that quantal content was low at the earliest stages of regeneration, but increased as the muscle fibres matured and became normal at 10‐21 days. 7. During repetitive stimulation at 30 Hz there was a fall in the amplitude of EPPs of 40‐45%. The fall was similar in regenerating and control fibres. Conducting synapses never exhibited failure to generate an EPP during the period of high‐frequency stimulation.
Effects of tibolone and conventional hormone replacement therapies on arterial and hepatic cholesterol accumulation and on circulating endothelin-1, vascular cell adhesion molecule-1, and E-selectin in surgically menopausal monkeys

ObjectiveMenopause and aging are associated with a marked increase in the incidence of coronary heart disease as well as reductions in circulating estrogen, progestogen, and androgen levels. The synthetic compound tibolone and its metabolites have estrogenic, progestogenic, and androgenic characteristics. In the present study, we compared the effects of tibolone, estrogen replacement therapy, and estrogen plus progestogen replacement therapy on arterial and hepatic lipid accumulation and on circulating soluble adhesion molecule and endothelin-1 concentrations in surgically postmenopausal cynomolgus monkeys. DesignAnimals were fed an atherogenic diet for 2 years while receiving either no hormone treatment (control, n = 31) or the following treatments at doses designed to mimic the human dose on a daily caloric intake basis: tibolone at 2.5 mg/day (HiTib, n = 31), tibolone at 0.625 mg/day (LoTib, n = 29), conjugated equine estrogens (CEE) alone at 0.625 mg/day (CEE, n = 29), or CEE plus continuous medroxyprogesterone acetate (MPA) at 2.5 mg MPA/day (CEE + MPA, n = 30). ResultsRelative to the control group, iliac artery total cholesterol content was not different in the HiTib, LoTib, and CEE + MPA groups but was significantly lower in the group receiving CEE only (P < 0.05). In contrast, hepatic free cholesterol content was reduced in all treatment groups [HiTib (P < 0.01), LoTib (P < 0.05), CEE (P < 0.01), and CEE + MPA (P < 0.05)], whereas hepatic total and esterified cholesterol content were reduced in the HiTib, CEE, and CEE + MPA groups (all P < 0.05). HiTib and CEE groups had lower hepatic triglyceride levels per milligram of protein (P < 0.05). Iliac arterial cholesterol content was highly correlated with hepatic cholesterol content and with previously published histomorphometrically determined coronary artery atherosclerosis, supporting the use of the iliac artery as a surrogate for the coronary artery in the monkey. Circulating levels of soluble vascular cell adhesion molecule-1 were significantly reduced in the HiTib (P < 0.02) and CEE (P < 0.05) groups, whereas soluble E-selectin was reduced in the CEE group only (P < 0.01). Plasma endothelin-1 was significantly reduced in the LoTib (P < 0.05), CEE (P < 0.01), and CEE + MPA (P < 0.01) groups. ConclusionsThese results suggest that while tibolone caused marked depression of high-density lipoprotein cholesterol and a resultant twofold increase in the total plasma cholesterol/high-density lipoprotein cholesterol ratio, those effects did not result in exacerbation of iliac artery atherosclerosis, perhaps because of beneficial effects on vascular biology or hepatic metabolism.
A 131.5GHz, −84dBm sensitivity super-regenerative receiver by zero-phase-shifter coupled oscillator network in 65nm CMOS

A CMOS high-sensitivity super-regenerative receiver is proposed for millimeter-wave imaging systems. With quench-control signals, two LC-tank oscillators are coupled in-phase by zero-phase-shifter network in a positive feedback loop. This leads to a high oscillatory amplification and improves the detection sensitivity. The circuit is realized in 65nm CMOS with a core area of 0.06 mm2. Measurements show that the receiver features a sensitivity of -84dBm, a noise-equivalent-power of 0.615fW/Hz0.5, a noise-figure of 7.26 dB and a power consumption of 8.1mW.
Parameterised Multiparty Session Types

For many application-level distributed protocols and parallel algorithms, the set of participants, the number of messages or the interaction structure are only known at run-time. This paper proposes a dependent type theory for multiparty sessions which can statically guarantee type-safe, deadlock-free multiparty interactions among processes whose specifications are parameterised by indices. We use the primitive recursion operator from Godel's System $\mathcal T$ to express a wide range of communication patterns while keeping type checking decidable. We illustrate our type theory through non-trivial programming and verification examples taken from parallel algorithms and Web services usecases.
Inhibition of adhesion of S-fimbriated Escherichia coli to buccal epithelial cells by human milk fat globule membrane components: a novel aspect of the protective function of mucins in the nonimmunoglobulin fraction

We investigated the presence of factors in human milk that inhibit invasion of pathogenic bacteria. The effect of human milk fat globule membrane (HMFGM) components on adhesion of cloned S-fimbriated Escherichia coli to human buccal epithelial cells was analyzed. S fimbriae are a common feature of E. coli strains causing sepsis and meningitis in newborns and are bound to epithelia via sialyl-(alpha-2-3)galactoside structures. Human milk fat globules (HMFG) could be agglutinated by the above-mentioned bacteria. Agglutination could be inhibited by fetuin, human glycophorin, and alpha 1-acid glycoprotein. In addition, pretreatment of HMFG with Vibrio cholerae neuraminidase markedly reduced bacterium-induced agglutinations, indicating the involvement of neuraminic acid-containing glycoproteins. In contrast, lipid droplets of infant formula or artificial lipid emulsions (Intralipid) could not be agglutinated. HMFG were present in stools of breast-fed neonates as shown by indirect immunofluorescence staining with a monoclonal antibody directed against carbohydrate residues present on HMFGM. These HMFG could be agglutinated by bacteria. HMFG inhibited E. coli adhesion to buccal epithelial cells. To further characterize relevant E. coli binding structures, HMFGM components were separated by gel chromatography. The mucin fraction showed the most pronounced inhibitory effect on adhesion of S-fimbriated E. coli to human buccal epithelial cells. Our data suggest that HMFG inhibit bacterial adhesion in the entire intestine and thereby may provide protection against bacterial infection.
Decreased cerebrospinal fluid/plasma ratio of the novel satiety molecule, nesfatin-1/NUCB-2, in obese humans: evidence of nesfatin-1/NUCB-2 resistance and implications for obesity treatment.

CONTEXT The novel adipokine, nesfatin-1/NUCB-2, reduces food intake, levels of which are elevated in overweight individuals. OBJECTIVES The aim of the study was to investigate the mechanisms underlying brain nesfatin-1/NUCB-2 uptake and to determine whether reduced uptake may contribute to nesfatin-1/NUCB-2 resistance. DESIGN Cerebrospinal fluid (CSF) and corresponding plasma nesfatin-1/NUCB-2 were measured by ELISA [18 men and 20 women; age, 19-80 yr; body mass index (BMI), 16.2-38.1 kg/m(2)] and correlated to body adiposity and metabolic parameters. RESULTS CSF/plasma nesfatin-1/NUCB-2 ratio was significantly negatively associated with BMI, body weight, fat mass, and CSF glucose. BMI was predictive of CSF/plasma nesfatin-1/NUCB-2 ratio (β = -0.786; P = 0.045). CSF nesfatin-1/NUCB-2 was significantly positively associated with plasma nesfatin-1/NUCB-2 (R = 0.706; P < 0.01). There was a significant linear relation between CSF and plasma nesfatin-1/NUCB-2 in lean (BMI <25 kg/m(2); R = 0.744; P = 0.002) and obese (BMI ≥ 30 kg/m(2); R = 0.693; P = 0.026) subjects. Subjects in the highest plasma nesfatin-1/NUCB-2 quintile had lower CSF/plasma nesfatin-1/NUCB-2 ratio [26.5% (26.0-29.5%)] compared to the lowest plasma nesfatin-1/NUCB-2 quintile [38.5% (34.0-42.0%)] (P < 0.01), corresponding BMI [32.4 (31.0-35.0) vs. 23.3 (19.7-23.5) kg/m(2); P < 0.01], and fat mass [32.8 (29.5-40.6) vs. 30.7 (8.2-20.1) kg/m(2); P < 0.01]. CONCLUSIONS Our observations have important implications with respect to the potential weight-reducing actions of nesfatin-1/NUCB-2 treatment. Future research should seek to clarify whether nesfatin-1/NUCB-2 would be beneficial in the management of obesity.
C. elegans sirtuin SIR-2.4 and its mammalian homolog SIRT6 in stress response

Stress is a significant life event. The immediate response to stress is critical for survival. In organisms ranging from the unicellular Saccharomyces cerevisiae to protozoa (Trypanosoma brucei) and metazoan (such as Caenorhabditis elegans, Homo sapiens) stress response leads to the formation of cytoplasmic RNA–protein complexes referred to as stress granules (SGs). SGs regulate cell survival during stress by the sequestration of the signaling molecules implicated in apoptosis. They are a transient place of messenger ribonucleoproteins (mRNPs) remodeling for storage, degradation, or reinitiation of translation during stress and recovery from stress. Recently, we have identified chromatin factor, the sirtuin C. elegans SIR-2.4 variant and its mammalian homolog SIRT6 as a regulator of SGs formation. SIRT6 is highly conserved NAD+-dependent lysine deacetylase and ADP-ribosyltransferase impacting longevity, metabolism, and cancer. We observed that the cellular formation of SGs by SIRT6 or SIR-2.4 was linked with the cell viability or C. elegans survival and was dependent on SIRT6 enzymatic activity. Here, we discuss how SIR-2.4/SIRT6 influences SGs formation and stress response. We suggest possible mechanisms for such an unanticipated function of a chromatin regulatory factor SIRT6 in assembly of stress granules and cellular stress resistance.
Automatic Referent Resolution of Deictic and Anaphoric Expressions

Deictic and anaphoric expressions frequently cause problems for natural language analysis. In this paper we present a single model that accounts for referent resolution of deictic and anaphoric expressions in a research prototype of a multimodal user interface called EDWARD. The linguistic expressions are keyed in by a user and are possibly accompanied by pointing gestures. The proposed model for reference resolution elaborates on Alshawi's (1987) notions of context factors and salience and integrates both linguistic and perceptual context effects. The model is contrasted with two alternative referent resolution models, namely, a simplistic one and the more sophisticated model proposed by Grosz and Sidner (1986). Based on empirical and analytical grounds, we conclude that the model we propose is preferable from a computational and engineering point of view.
Counselor training, anxiety, and counseling self-efficacy: Implications for training psychology students from the United Arab Emirates University.

The impact of training on counseling self-efficacy and state and trait anxiety was examined in this study. One hundred and thirteen undergraduate psychology students from United Arab Emirates (UAE) University participated in this investigation. The experimental group consisted of seventy-three students who were taking their first practicum (65 females; 8 males) and the control group was composed of female students who had not yet taken their practicum ( n = 40). Pre- and posttests were conducted using the Counseling Self-Estimate Inventory (COSE: Larson et al., 1992) and the State-Trait Anxiety Inventory (STAI: Spielberger, Gorsuch, & Lushene, 1970). Significant mean differences were found between the experimental group and the control group in both counseling self-efficacy and anxiety. Analysis of covariance revealed that training increased trainees' counseling self-efficacy and decreased their level of anxiety. These findings are discussed and directions for future research are provided.
‘Power is not an evil’: rethinking power in participatory methods

In recent years, participatory techniques have become popular amongst researchers working with children, both within geography and beyond. Using a focus group with primary school children as a point of departure, I argue for a reconceptualization of the power relations of participatory research. I draw on Foucault and De Certeau to theorize power in terms of strategies, tactics and the art of ‘making do’, concluding with some remarks about the distinctions between power, resistance and domination.
We Were, We Are, Will We Be? The Social Psychology of Collective Angst

Not all social groups survive the passage of time. Groups once in existence are now but memories of the past. If history is any indication, other social groups are likely to experience a similar fate and join the list of groups that once were. The concern that one’s group might one day join such a list is the focus of this paper. Specifically, we examine the social psychology of collective angst – a group-based emotion that stems from concern for the future vitality of one’s social group. We begin by discussing the anatomy of collective angst and how it differs from other collective emotions. We then outline factors that foster collective angst. Importantly, we provide a novel theoretical framework outlining both constructive and destructive means by which members may defend against a future that does not include their group. For example, we examine collective angst as a facilitator of, among other things, ingroup cohesion and outgroup aggression. Finally, we discuss how collective angst has manifested on the world stage as well as implications for relations within and between groups.
IMPACT OF TEACHER’S BEHAVIOUR ON THE ACADEMIC ACHIEVEMENT OF UNIVERSITY STUDENTS

This research article discusses the impact of teacher’s behaviour on the academic achievement of university students. All the teachers and students of public sector universities constituted the population. From the 15 public sector universities, 375 teachers and 1500 students from five departments were selected as a sample. Two questionnaires were developed and validated through pilot testing and administered to the sample for the collection of data. The researcher personally visited respondents, thus 100% data were collected. The collected data were tabulated and analyzed by using chi-square and Pearson’s product moment coefficient of correlation (r). The major conclusions of the study were that teachers felt proud to be teachers, they adjusted themselves with the prevailing situation and circumstances, and they used different motivational techniques for teaching. Students were found to be satisfied with the positive behaviour of their teachers. The relationship between the teachers’ behaviour and corresponding academic achievement (marks) revealed a highly positive significant correlation.
Managerial decision making under specific emotions

Purpose – The purpose of this paper is to investigate decision-processing effects of incidental emotions in managerial decision-making situations. Design/methodology/approach – A complex multi-attribute, multi-alternative decision task related to international human resources management is used as a research vehicle. The data are obtained by means of an electronic information board. Findings – Happiness and anger cause the decision maker to process less decision-relevant information, whereas fear activates more detail-oriented processing. The results are explained within the valence model and cognitive-appraisal framework. Research limitations/implications – A boundary condition of the study is the level of induced emotions. Processing effects of extremely high levels of emotions are not examined, which necessarily limits the generalizability of the findings. Also, the experiment focusses on the decision-processing effects of single isolated emotions extracted by manipulations; future research needs to ex.
Socle degrees of Frobenius powers

Let $k$ be a field of positive characteristic $p$, $R$ be a Gorenstein graded $k$-algebra, and $S=R/J$ be an artinian quotient of $R$ by a homogeneous ideal. We ask how the socle degrees of $S$ are related to the socle degrees of $F_R^e(S)=R/J^{[q]}$. If $S$ has finite projective dimension as an $R$-module, then the socles of $S$ and $F_R^e(S)$ have the same dimension and the socle degrees are related by the formula: $$D_i=qd_i-(q-1)a(R),$$ where $$ d_1\le >. \le d_{\ell}\quad\text{and}\quad D_1\le . \le D_{\ell}$$ are the socle degrees $S$ and $F_R^e(S)$, respectively, and $a(R)$ is the $a$-invariant of the graded ring $R$, as introduced by Goto and Watanabe. We prove the converse when $R$ is a complete intersection.
