Sensible Organizations: Changing Our Businesses and Work Styles through Sensor Data

We introduce the concept of sensor-based applications for the daily business settings of organizations and their individual workers. Wearable sensor devices were developed and deployed in a real organization, a bank, for a month in order to study the effectiveness and potential of using sensors at the organizational level. It was found that patterns of physical interaction changed dynamically while e-mail is more stable from day to day. Different patterns of behavior between people in different rooms and teams (p < 0.01), as well as correlations between communication and a worker's subjective productivity, were also identified. By analyzing a fluctuation of network parameters, i.e., “betweenness centrality, ” it was also found that communication patterns of people are different: some people tend to communicate with the same people in regular frequency (which is hypothesized as a typical pattern of throughput-oriented jobs) while some others drastically changed their communication day by day (which is hypothesized as a pattern of creative jobs). Based on these hypotheses, a reorganization, such that people having similar characteristics work together, was proposed and implemented.

Bilingual and Monolingual Brains Compared: A Functional Magnetic Resonance Imaging Investigation of Syntactic Processing and a Possible “Neural Signature” of Bilingualism

Does the brain of a bilingual process language differently from that of a monolingual? We compared how bilinguals and monolinguals recruit classic language brain areas in response to a language task and asked whether there is a “neural signature” of bilingualism. Highly proficient and early-exposed adult Spanish-English bilinguals and English monolinguals participated. During functional magnetic resonance imaging (fMRI), participants completed a syntactic “sentence judgment task” [Caplan, D., Alpert, N., & Waters, G. Effects of syntactic structure and propositional number on patterns of regional cerebral blood flow. Journal of Cognitive Neuroscience, 10, 541–552, 1998]. The sentences exploited differences between Spanish and English linguistic properties, allowing us to explore similarities and differences in behavioral and neural responses between bilinguals and monolinguals, and between a bilingual's two languages. If bilinguals' neural processing differs across their two languages, then differential behavioral and neural patterns should be observed in Spanish and English. Results show that behaviorally, in English, bilinguals and monolinguals had the same speed and accuracy, yet, as predicted from the Spanish-English structural differences, bilinguals had a different pattern of performance in Spanish. fMRI analyses revealed that both monolinguals (in one language) and bilinguals (in each language) showed predicted increases in activation in classic language areas (e.g., left inferior frontal cortex, LIFC), with any neural differences between the bilingual's two languages being principled and predictable based on the morphosyntactic differences between Spanish and English. However, an important difference was that bilinguals had a significantly greater increase in the blood oxygenation level-dependent signal in the LIFC (BA 45) when processing English than the English monolinguals. The results provide insight into the decades-old question about the degree of separation of bilinguals' dual-language representation. The differential activation for bilinguals and monolinguals opens the question as to whether there may possibly be a “neural signature” of bilingualism. Differential activation may further provide a fascinating window into the language processing potential not recruited in monolingual brains and reveal the biological extent of the neural architecture underlying all human language.

All Mothers are Not the Same: Maternal Styles in Bottlenose Dolphins (Tursiops truncatus)

A dolphin calf’s relationship with its mother is crucial for its survival and may be affected by the mother’s preferred mode of interacting with her calf. Mothers from a variety of species exhibit individual differences and stable maternal styles. However, little is known about individual differences in the maternal behaviors of dolphins. We investigated the possibility of maternal styles in dolphins by identifying specific maternal care behaviors in 7 dolphin mothers at two facilities during the first year of each calf’s life. The mothers exhibited different patterns of behavior including proximity maintenance, discipline, and initiation of separations and reunions with calves. These patterns of maternal behaviors suggest that dolphin mothers display a range of maternal styles that appear to be differentiated by level of maternal control. Moreover, a mother may also modify her individual style as her calf matures and as the social context changes.

Preobesity in the infant OLETF rat: The role of suckling

The Otsuka Long Evans Tokushima Fatty (OLETF) rat model of obesity, which lacks CCK(1) receptors, has been extensively investigated over the last decade. We have recently focused on the early developmental stages of this strain, finding that OLETF pups are heavier than controls from birth and hyperphagic already from postnatal (PN) Day 2. OLETF mothers present differential maternal behavior patterns and increased nursing time and frequency, which might contribute to the preobese characteristics of the pups. The present investigation examined the pups' ability to gain weight from the nursing episodes. First, we measured the pups' weight gain from one nursing bout from their own dam. Next we examined the pups' weight gain after a feeding competition test with control pups from foster dams of both strains. OLETF pups gained more weight than controls from their own dams on PN Week 1 due to a higher suckling rate (and/or efficacy) and on PN Week 3 due to increased nursing time. When competing with control pups, OLETF pups gained significantly more weight after the same nursing bout, regardless of the strain of the mother. Body mass index (BMI) was significantly higher in OLETF pups compared to controls. The maternal parameters assessed from the experiment were latencies to pup retrieval and to nursing, and nursing duration; differences were only observed in nursing time. OLETF dams increased their average nursing time over the PN weeks, while control dams decreased their nursing time toward weaning. The results suggest an important contribution of OLETF pups toward their own preobese development.

Effect of Thickening Agent and Fat in Custard Microstructure Upon in vitro Enzymatic Digestion

Custards desserts with and without fat were prepared using either tapioca modified starch or carboxymethylcellulose (CMC) as thickening agents and the changes in their microstructure upon in vitro simulation of mouth, stomach, and small intestine conditions were evaluated by light microscopy. A completely different pattern of behavior was found between starch and CMC custards. After mouth incubation, the partially gelatinized tapioca granules were completely disintegrated by the action of saliva, while the CMC custard is practically unaffected. Fat incorporation did not influence the breakdown of gelatinized starch. Coagulation of the milk protein is observed after stomach incubation. In the starch custards, the fat globules do aggregate with the milk protein, while in the CMC custard they are still embedded in the unaltered network. Intestine incubation completely digests the remaining structures after stomach incubation, although in the CMC custard particles of undigested hydrocolloid are observed. In the presence of fat, micelles are visualized in both custards, which favor the bioaccessibility of lipophilic compounds. The higher digestive resistance of the CMC custards implied the existence of a higher barrier against the release of active compounds from the custard matrix and therefore a higher barrier against bioaccessibility.

Parent versus Teacher Ratings of Attention-Deficit/Hyperactivity Disorder Symptoms in the Preschoolers with Attention-Deficit/Hyperactivity Disorder Treatment Study (PATS)

To assess parent-teacher concordance on ratings of DSM-IV symptoms of attention-deficit/hyperactivity disorder (ADHD) in a sample of preschool children referred for an ADHD treatment study. Parent and teacher symptom ratings were compared for 452 children aged 3-5 years. Agreement was calculated using Pearson correlations, Cohen's kappa, and conditional probabilities. The correlations between parent and teacher ratings were low for both Inattentive (r = .24) and Hyperactive-Impulsive (r = .26) symptom domains, with individual symptoms ranging from .01-.28. Kappa values for specific symptoms were even lower. Conditional probabilities suggest that teachers are only moderately likely to agree with parents on the presence or absence of symptoms. Parents were quite likely to agree with teachers' endorsement of symptoms, but much less likely to agree when teachers indicated that a symptom was not present. Results provide important data regarding base rates and concordance rates in this age group and support the hypothesis that preschool-aged children at risk for ADHD exhibit significant differences in behavior patterns across settings. Obtaining ratings from multiple informants is therefore considered critical for obtaining a full picture of young children's functioning.

Factors affecting the combustion toxicity of polymeric materials

Fire gas toxicity is an essential component of any fire hazard analysis. However, fire toxicity, like flammability, is both scenario and material dependent. A number of different methods exist to assess the fire toxicity, but many of them fail to relate this to a particular fire scenario. Sample thickness alone, in a closed box test such as the NBS Smoke Chamber, is shown to change the fire scenario from well-ventilated to under-ventilated. Data from two flow-through tests, the static tube furnace (NF X 70-100) and the steady state tube furnace (the Purser furnace, BS 7990 and ISO TS 19700) show that there are different patterns of behaviour for different polymers (LDPE, polystyrene, rigid PVC and Nylon 6.6). The predicted toxicities show variation of up to two orders of magnitude with change in fire scenario. They also show change of at least one order of magnitude for different materials in the same fire scenario. Finally, they show that in many cases CO, which is often assumed to be the most, or even the only toxicologically significant fire gas, is of less importance than either HCl, or HCN, when present, and in some cases less important than organo-irritants. Nylon 6.6 shows the highest predicted toxicity, the greatest scenario dependence, and the least sensitivity to different apparatuses, while polystyrene shows the highest sensitivity to the different apparatuses, but the lowest to different fire scenarios. PVC shows high toxicity, mostly due to HCl in the fire effluent, under all fire conditions, and LDPE shows a more progressive increase in toxicity from well-ventilated flaming to both smouldering and under-ventilated flaming.

Comprehension of sexual situations and its relationship to risky decisions by young adults

This research examines the nature of the relationship between comprehension of sexual situations and decisions about risky sexual behaviour by young adults. Participants were 56 heterosexual students from Brooklyn College, NY, located in a community with a relatively high prevalence of HIV/AIDS. They read a sexual encounter scenario and verbally responded to open-ended questions and made decisions about condom use. The responses were recorded, transcribed and analysed. Prior beliefs were evaluated based on participants’ initial responses to the scenario. High and low risk individuals showed a specific set of beliefs about safer sex practices, and they processed information differently during comprehension of the sexual situation. Low-risk individuals focused on cues that show “risks of unprotected sex”, with the goal of not taking any risks. High-risk individuals processed given information as emotionally related, with the goal of ‘immediate pleasure’ in the situation. These processing variables influenced the young adults’ decisions to practice (or not) safer sex behaviour. Educational interventions need to be tailored for different patterns of behaviour. The goal of a customization approach is to intervene at appropriate weak links in the decision-making process, including any contradictory or unjustified beliefs, to promote safer sex behaviour.

Growth‐mortality tradeoffs and ‘personality traits’ in animals

Consistent individual differences in boldness, reactivity, aggressiveness, and other 'personality traits' in animals are stable within individuals but vary across individuals, for reasons which are currently obscure. Here, I suggest that consistent individual differences in growth rates encourage consistent individual differences in behavior patterns that contribute to growth-mortality tradeoffs. This hypothesis predicts that behavior patterns that increase both growth and mortality rates (e.g. foraging under predation risk, aggressive defense of feeding territories) will be positively correlated with one another across individuals, that selection for high growth rates will increase mean levels of potentially risky behavior across populations, and that within populations, faster-growing individuals will take more risks in foraging contexts than slower-growing individuals. Tentative empirical support for these predictions suggests that a growth-mortality perspective may help explain some of the consistent individual differences in behavioral traits that have been reported in fish, amphibians, reptiles, and other animals with indeterminate growth.

Predictors of calcium intake patterns: A longitudinal analysis.

The study was guided by the precaution adoption process model; the author examined factors associated with (a) stage of change with respect to calcium intake at 4 time points and (b) calcium intake patterns across time. Data were collected by mailed questionnaire at baseline and at 3 follow-up assessments over 1 year. The primary outcome measures were calcium intake, stage of change with respect to calcium intake, and pattern of calcium intake across follow-up. Three patterns were identified: successful maintenance (adequate calcium intake at all 3 follow-ups), vacillation (adequate calcium consumption at 1 or 2 follow-ups), and inertia (inadequate calcium consumption at all 3 follow-ups). Five hundred six women completed baseline questionnaires, and 346 completed 3 follow-up assessments. Even after baseline stage of change was controlled for, longitudinal analyses revealed 3 variables that predicted different patterns of behavior across time. Isolated instances of adequate calcium intake were predicted by higher levels of knowledge and perceived benefits, whereas long-term maintenance was predicted by lower levels of perceived difficulty. These findings provide support for a central premise of the model, that different factors are important at different points in the behavior change process.

Different orientations of males and females in computer-mediated negotiations

This paper examines the existence of gender differences in computer mediated (CM) negotiations where “gender differences” refers to the differential patterns of behavior of males and females proposed by Rubin and Brown (Rubin, J. Z., & Brown, B. R. (1975). Bargainers as individuals. In The social psychology of bargaining and negotiation (pp. 157–196). New York: Academic Press). Namely, males are more profit oriented and females are more relationship oriented. External manipulations encouraging cooperativeness with other negotiators either by profitable or social incentives were inserted in the negotiations performed within the Colored Trails (CT) game framework. The negotiators included 27 females and 33 males who negotiated in foursomes via computers. In the first study we focused on independent negotiators whose success was not crucially dependent on the other party. In the second study negotiators were dependent upon one another, encouraging integrative solutions. The findings reveal that the social incentive (team factor) positively affected the females’ cooperativeness in contrast to males who were slightly less cooperative. On the other hand, profitable incentive influenced the males’ cooperativeness level, while no change was shown by females, which is consistent with Rubin and Brown’s distinction. These tendencies were reduced when playing with a non-reciprocal simulated agent. The causes for gender differences in CM as well as in face-to-face (FTF) negotiations are discussed.

AHP-Group Decision Making: A Bayesian Approach Based on Mixtures for Group Pattern Identification

This paper proposes a Bayesian estimation procedure to determine the priorities of the Analytic Hierarchy Process (AHP) in group decision making when there are a large number of actors and a prior consensus among them is not required. Using a hierarchical Bayesian approach based on mixtures to describe the prior distribution of the priorities in the multiplicative model traditionally used in the stochastic AHP, this methodology allows us to identify homogeneous groups of actors with different patterns of behaviour for the rankings of priorities. The proposed procedure consists of a two-step estimation algorithm: the first step carries out a global exploration of the model space by using birth and death processes, the second concerns a local exploration by means of Gibbs sampling. The methodology has been illustrated by the analysis of a case study adapted from a real experiment on e-democracy developed for the City Council of Zaragoza (Spain).

Breeding behaviour and parental care in the Griffon Vulture Gyps fulvus on the island of Crete (Greece)

A field study of the breeding behaviour of griffon vultures (Gyps fulvus) was conducted in Crete (Greece) during 1997–2000. The main behavioural patterns examined were aerial displays, nest defence, copulation, nest building, brooding and food provisioning to the chicks. The nesting territory consisted of a semicircle ca 5 m radius around the nest that was defended against conspecifics. Copulation attempts mainly occurred in the nesting ledge with a success rate of 77%. On average every pair accomplished 0.16 ± 0.34 copulations per day (range = 0–4) while 3.3% of the total attempts accounted for extra–pair copulations. Supplying material to the nest started 32 ± 9 days prior to egg laying (range = 17–44) at a rate of 5 ± 3.52 bouts/pair/day (range = 1–14).The mean number of items added to the eyrie was 2 ± 1.3/bout/pair (range = 1–8) with 63.5% of these being soft greenery.The mean frequency of relief at the nest relieves was 0.5 ± 0.64 bouts/pair/day (range = 0–2) while an incubation shift lasted on average 37.4 ± 0.5 hr (range = 25.6–50.2 hr). Nest attendance by breeding birds was continuous during the first 2 months after the hatching of the egg, dropping to 35% of daytime hours before fledging. Adult griffons foraged on average every other day while food delivery rate to the chick was calculated at 1.9±1.09 bouts/pair/day (range = 1–4). The most critical period of the reproductive cycle was May when chicks (6–10 weeks old) grew at their fastest rate and parent birds foraged on alternate days. Differences in behavioural patterns among this insular population and continental ones were minimal.

Is there a ‘New Managerial Work’? A Comparison with Henry Mintzberg's Classic Study 30 Years Later*

abstract This comparative study of top executives' work aimed at examining the stability of top managerial behaviour reveals a relatively different pattern of behaviour compared with the study by Henry Mintzberg. The main differences are a much larger workload, a contact pattern to a larger degree oriented towards subordinates in group‐settings, a greater emphasis on giving information, and less preoccupation with administrative work. One important finding is that fragmentation of time – in previous studies highlighted as a central tenet of managerial work – was not as prevalent in the new study. The different results can be attributed (with caution) to the impact of the management discourse about leadership and corporate culture, and to factors such as organizational structure and geographical dispersion of companies. However, there are also significant similarities between the two studies which indicate that claims of the emergence of a radically different managerial work are much exaggerated. Instead the empirical data shows that new work‐practices are combined with older practices, both in a complex and context‐specific ways. Therefore, there is a need for better integration between theoretical development and empirical investigations in this field of inquiry.

Dissociation of physiology and behavior in PTSD

We have previously reported that subjects with posttraumatic stress disorder (PTSD) differ from trauma controls in their ability to produce and withhold responses in the Stop-Signal Task depending on the motivational context as determined by financial reward. This experiment measured skin conductance and heart rate to assess autonomic changes accompanying these different patterns of behavior. Fowles hypothesized that heart rate would increase with behavioral activation and that increases in skin conductance would accompany behavioral inhibition. Both PTSD and comparison groups showed the expected behavioral changes in response to rewards, but they differed in their physiological responses. The subjects in the traumatized comparison group showed changes in skin conductance and heart rate consistent with Fowles' hypothesis and the observed changes in behavioral inhibition and activation. However, PTSD subjects showed no significant change in either physiological measure. These results demonstrate a dissociation between autonomic reactivity and motivated behavior in PTSD that may represent one aspect of emotional numbing.

Aggregation Properties of Hyperporphyrins with Hydroxyphenyl Substituents

Acidification of tetrakis(4-hydroxyphenyl)porphyrin (THPP) and tetrakis(3,5-dihydroxyphenyl)porphyrin (OHPP) in dichloromethane solutions has been investigated as a function of the nature of the counteranion. These porphyrins exhibit different patterns of behavior, and extended aggregates are formed displaying broad extinction features together with intense components due to resonant light scattering. Especially in the case of haloacids, J-aggregated species are obtained exhibiting large bathochromic shifts both for B- and Q-bands, which extend in the far red region. The optical characteristics of the aggregated and monomeric protonated species are strongly influenced by the nature of the counteranions. A comparison with tetrakis(4-methoxyphenyl)porphyrin (TMPP), which remains always in a monomeric form, demonstrates the key role played by the peripheral hydroxyl groups in stabilizing various porphyrin aggregates.

Israeli counsellors facing terrorism: coping and professional development

ABSTRACT The current study examined the characteristics and functioning of 12 Israeli school counsellors located at different stages of professional development who worked in schools affected by terrorist attacks. Semi-structured interviews explored the counsellors’ professional behaviour, activities, and coping with terror and its effects. Consensual qualitative research analysis revealed five major domains: role definition, organisational characteristics, affective reactions, dilemmas, and barriers and resources. Counsellors at different stages of professional development demonstrated different patterns of behaviour across the domains’ categories and subcategories. Implications for research and supervision are discussed.

Genetic and immunological factors interact in a mouse model of CNS antiphospholipid syndrome

The antiphospholipid syndrome (APS) includes systemic and central nervous system (CNS) pathology associated with antibodies to a complex of phospholipids and β 2-glycoprotein I (β 2-GPI). We have recently reported the induction of APS associated with behavioral and cognitive deficits in BALB/c female mice that developed 4–5 months after immunization with β 2-GPI. In the present study, we examined the influence of genetic factors on the ability to induce experimental APS with CNS involvement by testing several mouse strains immunized with β 2-GPI. Female mice from five strains were immunized once with β 2-GPI in complete Freund's adjuvant (CFA) or with CFA alone (controls). Autoantibody levels were examined at 1 and 5 months after immunization. Neurological assessment in a staircase test was performed 4–5 months following the immunization. Induction of APS resulted in elevated levels of antibodies against negatively charged phospholipids and β 2-GPI in all five mouse strains. Autoantibody levels were significantly higher in Balb/c, ICR, and C57BL/6 mouse strains compared to AKR and C3H. aPL levels dropped significantly more in the C57BL/6 compared to Balb/c mice over a period of 4 months. Hyperactivity reflected by higher number of stairs climbed in 3 min, was induced by APS in the Balb/c and ICR, mouse strains. Exploratory behavior reflected by more frequent rears, was seen in the APS-Balb/c and AKR mice. Hypoactivity and less exploration were seen in the APS-C57BL/6 and C3H mice. The study supports a link between high levels of aPL and behavioral changes in a mouse APS model. Qualitative differences in behavioral patterns may be due to nervous system as well as immune genetic factors. The minimal effect of APS in C57BL/6 mice may provide a suitable background for the study of transgenes in these mice.

The effects of micro-cultural differences on consumer behaviour: the case of differences in the buying behaviours of Christian and Muslim consumers

This paper examines the effects of micro-cultural differences on buying behaviour, especially with regard to electrical and home appliances. Sixty-six Christian and Muslim consumers, citizens of a multicultural town, participated in 11 focus groups to allow the authors to examine the differences in the consumers' perceptions, attitudes and purchasing behaviour. The research took place in Komotini, a Greek town where Christian and Muslim consumers, with differences in religion and in other micro-cultural factors, have coexisted for decades. Results reveal that microculture develops different patterns of behaviour for Christian and Muslim consumers, based on their religious preferences and social class. Differences were also found between Christian and Muslim consumers in their perceptions of the ideal store, as well as in their buying selection criteria. The results suggest that micro-cultural differences have to be incorporated in retailers' marketing strategies in multicultural societies.

Psychosocial Intimacy and Identity

Age and gender differences in patterns of behavior and experience, cognitive beliefs, affective involvement, and psychosocial functioning in romantic relationships were observed in 473 adolescents and emerging adults (ages 12-24). Older adolescents indicated more dating experiences, times in love, passion, identity, and intimacy. They also reported more commitment-related romantic beliefs but less romantic idealization. Across all grades, females indicated fewer times in love and less tendency to believe in love at first sight but greater intimacy and self-consciousness. In addition, predictions of psychosocial intimacy were examined. For both males and females, greater intimacy was associated with less self-consciousness but more passion, commitment-related beliefs, and psychosocial identity. Implications for creating empirically based resources for facilitating positive development in adolescents’ interpersonal lives are discussed.
