Association between Adversity and Prosociality in Children Exposed to Trauma in Four Sites in West Africa
Creators: Ghailian, Monica
Publisher: name: Columbia University
Year: 2013
Subjects: Clinical psychology

description: The negative effects of trauma exposure on youth behavior and mental health has included internal disturbances that cause distress to the individual, as well as, externalizing behaviors that cause distress to others.  Researchers have also argued that trauma exposure can have a positive impact on psychosocial development, in that it can lead people to align with others, rather than turn against them. In an effort to identify factors that might nullify the association between trauma exposure and subsequent negative consequences, this paper examines the relationship between trauma exposure and prosocial behavior in Sierra Leone, Togo, Burkina Faso and Liberia. Results indicate that total trauma exposure was negatively associated with prosocial behavior in Sierra Leone and Liberia, while the inverse relationship was found in Togo and Burkina Faso, where trauma exposure was shown to have a positive association with prosocial behavior. The effect of trauma exposure on prosocial behavior varied by gender in Togo; among girls, trauma exposure had a positive significant association with prosocial behavior, however it did not impact prosocial behavior among boys. Lastly, the negative impact of trauma exposure on prosocial behavior found in Sierra Leone is partially explained by the indirect effect of PTSD and depression. Results are discussed in the context of individual and environmental differences that promote risk or resilience. Limitations and future implications for research, and practice are discussed.

New constraints on the mass bias of galaxy clusters from the power spectra of the thermal Sunyaev-Zeldovich effect and cosmic shear

description: Thermal Sunyaev-Zeldovich (tSZ) power spectrum is a powerful probe of the present-day amplitude of matter density fluctuations, and has been measured up to $\ell\approx 10^3$ from the {\it Planck} data. The largest systematic uncertainty in the interpretation of this data is the so-called "mass bias" parameter $B$, which relates the true halo mass to the mass proxy used by the {\it Planck} team as $M_{\rm 500c}^{Planck}=M_{\rm 500c}^{\rm true}/B$. Since the power spectrum of the cosmic weak lensing shear is also sensitive to the amplitude of matter density fluctuations via $S_8\equiv σ_8 Ω_m^α$ with $α\sim 0.5$, we can break the degeneracy between the mass bias and the cosmological parameters by combining the tSZ and cosmic shear power spectra. In this paper, we perform a joint likelihood analysis of the tSZ power spectrum from {\it Planck} and the cosmic shear power spectrum from Subaru Hyper Suprime-Cam. Our analysis does not use the primordial cosmic microwave background (CMB) information. We obtain a new constraint on the mass bias as $B = 1.37 ^{+0.15}_{-0.23}$ or $(1-b) = B^{-1}=0.73^{+0.08}_{-0.13}$ (68\%~C.L.), for $σ_8 < 0.9$. This value of $B$ is lower than that needed to reconcile the tSZ data with the primordial CMB and CMB lensing data, i.e., $B = 1.64 \pm 0.19$, but is consistent with the mass bias expected from hydrodynamical simulations, $B = 1.28 \pm 0.20$. Our results thus indicate that the mass bias is consistent with the non-thermal pressure support from mass accretion of galaxy clusters via the cosmic structure formation, and that the cosmologies inferred from the tSZ and the cosmic shear are consistent with each other.

Assistive Visual Tools For Surgery

Subjects: Computer science

description: This thesis describes efforts towards the development of computational vision tools to assist physicians during surgical procedures. Surgical robotics has come a long way towards improving patient care and enhancing the abilities of the surgeon. It was originally introduced to address the limitations of manual laparoscopy, whereby long rigid tools are being used to perform complicated surgical procedures. However, as we continue to reduce the invasiveness of this hardware and the tools becomes more complicated (e.g., flexible, articulated), intelligent algorithms are necessary to assist the surgeon in both controlling the surgical robot and making it smarter. Tool tracking algorithms are investigated to extract the locations of the surgical tools in both 2-dimensions (for visual servoing of a motorized camera system) and 3-dimensions (for situational awareness, increased patient safety, and virtual measuring capabilities). This work is shown in real surgical scenarios, such as manual human laparoscopies as well as robotic procedures using Intuitive Surgical's da Vinci robot. Additionally, newer procedural paradigms which reduce the invasiveness of surgical access (e.g., Single-Port Access (SPA), Natural Orifice Translumenal Endoscopic Surgery (NOTES)) require more flexible and dexterous hardware. Vision is used to measure the state of continuum ("snake") robots in order to provide feedback to control systems and be able to perform fully-automated, closed-loop actions (e.g., suturing, biopsies, etc). This work is performed on the Insertable Robotic Effector Platform (IREP), which is a dexterous, 2-arm snake manipulator with a motorized stereo camera system designed for SPA/NOTES procedures.

description: The microscopic dynamics in liquid gallium (l-Ga) at melting (T=315 K) has been studied by inelastic x-ray scattering. We demonstrate the existence of collective acoustic-like modes up to wave-vectors above one half of the first maximum of the static structure factor, at variance with earlier results from inelastic neutron scattering data [F.J. Bermejo et al. Phys. Rev. E 49, 3133 (1994)]. Despite the structural (an extremely rich polymorphism and rather complex phase diagram) and electronic (mixed valence) peculiarity of l-Ga, its collective dynamics is strikingly similar to the one of Van der Walls and alkali metals liquids. This result speaks in favor of the universality of the short time dynamics in monatomic liquids rather than of system-specific dynamics.

description: We explore the constraints that can be placed on the evolutionary timescales for typical low redshift galaxies evolving from the blue cloud through the green valley and onto the red sequence. We utilise galaxies from the GAMA survey with 0.1 < z < 0.2 and classify them according to the intrinsic (u-r?) colours of their stellar populations, as determined by fits to their multi-wavelength spectral energy distributions. Using these fits to also determine stellar population ages and star formation timescales, we argue that our results are consistent with a green valley population dominated by galaxies that are simply decreasing their star formation (running out of gas) over a timescale of 2-4 Gyr which are seen at a specific epoch in their evolution (approximately 1.6 e-folding times after their peak in star formation). If their fitted star formation histories are extrapolated forwards, the green galaxies will further redden over time, until they attain the colours of a passive population. In this picture, no specific quenching event which cuts-off their star formation is required, though it remains possible that the decline in star formation in green galaxies may be expedited by internal or external forces. However, there is no evidence that green galaxies have recently changed their star formation timescales relative to their previous longer term star formation histories.

description: Harry hides on an edge of a graph and does not move from there. Sally, starting from a known origin, tries to find him as soon as she can. Harry's goal is to be found as late as possible. At any given time, each edge of the graph is either active or inactive, independently of the other edges, with a known probability of being active. This situation can be modeled as a zero-sum two-person stochastic game. We show that the game has a value and we provide upper and lower bounds for this value. Finally, by generalizing optimal strategies of the deterministic case, we provide more refined results for trees and Eulerian graphs.

Association of Maternal Cumulative Risk during Pregnancy and IQ in Preschoolers: Role of Glucocorticoids and their Receptors
Creators: Beckmann, Katherine Anne
Publisher: name: Columbia University
Year: 2012
Subjects: subject: Developmental psychology
subject: Genetics
subject: FOS: Biological sciences

description: There may be a cumulative effect of social and environmental risk factors which lead to chronic, elevated levels of stress. Constant elevations of maternal stress hormones during pregnancy disrupt developing fetal brain chemistry and architecture, resulting in later memory and learning deficiencies. While we know that the quality of the fetal environment and the timing of exposure to a variety of substances are critical for developmental and health outcomes, little is known about the consequences of maternal cumulative risk on the fetus and later cognitive development. With data from the Nurse Family Partnership Elmira Sample, this work investigates whether maternal cumulative risk during pregnancy predicts IQ in 3 and 4 year olds, without and with postnatal influences. The role that birth outcomes play as mediators of this relationship is also explored. Finally, moderation effects and cumulative genetic risk of five polymorphisms of the glucocorticoid receptor (GR) gene are examined. Increased maternal cumulative risk during pregnancy was negatively associated with IQ at ages 3 and 4 with and without the inclusion of postnatal controls. Birth outcomes partially mediated this relationship to a small extent. GR rs6198 G and rs6190 G alleles infer risk while rs6198 A alleles serve as protective factors with respect to the association of maternal cumulative risk during pregnancy and IQ in young children. This study contributes insights on the cumulative effects of chronic social and environmental stressors that may lead to increased levels of maternal stress hormones during pregnancy and poor cognitive outcomes in young children in the presence of specific glucocorticoid receptor single nucleotide polymorphisms. Application of findings to early intervention programming and policy is discussed.

description: We present a new set of galaxy scaling relations for the relative mass content of atomic gas, molecular gas and stars. Such relations are driven by disc gravitational instability, and originate from the low galaxy-to-galaxy variance of Toomre's $Q$ stability parameter. We test such relations using more than 100 galaxies, from massive spirals to dwarf irregulars, thus spanning several orders of magnitude in stellar mass ($M_{\star}\approx10^{6\mbox{-}11}\,\mbox{M}_{\odot}$) and atomic gas mass ($M_{\mathrm{HI}}\approx10^{7\mbox{-}10.5}\,\mbox{M}_{\odot}$). Such tests demonstrate (i) that our scaling relations are physically motivated and tightly constrained, (ii) that the mass-averaged gravitational instability properties of galaxy discs are remarkably uniform across the sequence Sa-dIrr, and (iii) that specific angular momentum plays an important role in such a scenario. Besides providing new insights into a very important topic in galaxy evolution, this work provides a simple formula (Eq. 5) that one can use for generating other galaxy relations driven by disc instability. We explain how to do that, mention a few possible applications, and stress the importance of testing our approach further.

description: The article gives an analysis of the possibilities and limits of the concept of ecological modernization. The concept was used already in the early 1980s to describe the common field of ecology and economy. The focus was on technological progress reducing the environmental impact of production and consumption. Hajer and other authors had a broader definition of the concept. But it could make sense to differentiate technical / non-technical solutions (the latter being less compatible with the economic system). The limits to eco-modernization strategies and the need for “structural” solutions could possibly better be demonstrated by the earlier concept. A policy for ecological modernization may be defined as the sum of government actions aimed to stimulate environmental innovations and their diffusion. Higher eco- efficiency - instead of end-of-pipe measures - is its main objective. But innovation is a highly difficult task, especially for governments. No simple “instrumentalistic” solution is available. Therefore, a more complex policy pattern will be necessary. A more global policy approach would be the stimulation of “green” lead markets. As a rule a complex interplay between political and technical innovation and diffusion can be observed.
Three-block exceptional collections over Del Pezzo surfaces

description: We study complete exceptional collections of coherent sheaves over Del Pezzo surfaces, which consist of three blocks such that inside each block all Ext groups between the sheaves are zero. We show that the ranks of all sheaves in such a block are the same and the three ranks corresponding to a complete 3-block exceptional collection satisfy a Markov-type Diophantine equation that is quadratic in each variable. For each Del Pezzo surface, there is a finite number of these equations; the complete list is given. The 3-string braid group acts by mutations on the set of complete 3-block exceptional collections. We describe this action. In particular, any orbit contains a 3-block collection with the sum of ranks that is minimal for the solutions of the corresponding Markov-type equation, and the orbits can be obtained from each other via tensoring by an invertible sheaf and with the action of the Weyl group. This allows us to compute the number of orbits up to twisting.

In this paper we study those Kaehler manifolds $(M, g)$ admitting a finite TYCZ expansion. We show that if the TYCZ expansion is finite then $T_{mg}$ is indeed a polynomial in $m$ of degree $n$, $n=dim M$, and the log-term of the Szegö kernel of the disc bundle $D\subset L^*$ vanishes (where $L^*$ is the dual bundle of $L$). Moreover, we provide a complete classification of the Kaehler manifolds admitting finite TYCZ expansion either when $M$ is a complex curve or when $M$ is a complex surface with a cscK metric which admits a radial Kaehler potential.

description: Childhood obesity is a serious public health concern, yet evidence linking childhood obesity and related modifiable behaviors is lacking. This study examines cross-sectional associations among two measures of weight status, energy balance related behaviors (EBRB), and psychosocial mediators. Participants included children (N=1382) who participated in baseline assessments for the Food, Health and Choices childhood obesity study during Spring and Fall 2012. Participants were mostly low-income Hispanic and Black children, ages 9-13, from New York City public elementary schools in upper Manhattan and the Bronx. Body mass index percentile for age (BMI) and percent body fat (%BF) were calculated using a Tanita body composition analyzer and stadiometer. The Food, Health and Choices Questionnaire (FHC-Q), administered in participating classrooms, measured self-reported EBRB, such as sweetened beverage intake and physical activity frequency, as well as psychosocial mediators, such as outcome expectations and autonomy. Statistical analyses included Pearson correlations, regression analyses, one-way ANOVA, ANCOVA, and descriptive statistics. Despite a high correlation between BMI and %BF, a wide range of %BF was observed for each category of weight status determined by BMI: underweight, normal weight, overweight, and obese. Unexpectedly, slight but significant inverse correlations were observed between BMI/%BF and processed packaged snack and sweetened beverage intake. Overweight and obese children reported healthier EBRB than normal weight children. Mediator analyses identified habit strength as a predictive variable for most EBRB. Means for mediator scales indicated healthier levels of autonomous motivation, competence, goal setting skills, behavioral intentions, and outcome expectations among overweight and obese children compared to normal weight children. Results suggest more healthful behaviors and mediators may already be in place in overweight/obese children compared to normal weight children. However, EBRB for all children was far removed from current dietary and activity recommendations indicating room for improvement in this population. Further investigation of associations among childhood obesity, EBRB, and psychosocial mediators is warranted, as is the development of %BF standards for children.
Modern Applied Botany: Changes in the perception of applied botanists to themselves and others during the last century.

description: Subsequent to a short chronicle of the history of applied research in plant biology in Germany, the relevance of modern Applied Botany is illustrated by three relevant post-harvest processes. The metabolic reactions that play a key role in the determination of quality of the related plant-derived commodities from each are presented. Increased understanding of the processes involved in these processes has facilitated improvement of product quality in the resulting products. In each instance, it has been necessary to regard plant metabolism comprehensively and not to focus on a single physiological process. Moreover, the various interactions with the environment have to be considered. These illustrations demonstrate that transfer and application of basic plant knowledge into product-related research can provide significant information that is valuable for improvement of plant-derived products. In some instances, these correlations can even account for traditional and well-established processes, as illustrated for the malting process. However, interdisciplinary work and intensive cooperation with growers and producers must be an integral part of developing feasible and economically acceptable solutions that can be transferred into practice. Ultimately, the major challenge in Applied Botany today is the implementation of new concepts and ideas into product-related research. In consequence, modern Applied Botany acts as a mediator between basic plant science and industrial, product-related research.

description: Plant-derived sulfur-containing secondary metabolites constitute a small group of low-molecular weight natural products, which play a vital role in plant-pest interactions in numerous plant families andrepresent major defense molecules in the Asteraceae, Alliaceae, and Brassicaceae families. In this review we highlight the crucial role of environmental stress factors in the production of S-containing secondary metabolites. Furthermore, we describe a serendipitous variety of plant-derived sulfur-containing natural products produced or induced under biotic and abiotic stress and their structural diversity, promising pharmacological properties for use by humans, and beneficial effects for plants. Specifically, cruciferous phytoalexins are known as elicit plant defense molecules. Glucosinolates are candidates for tumorpreventive effects. Cysteine sulfoxides found in garlic are considered as profound antimicrobial agents. In this review, we discuss types of S bonds in the molecules and their relevance for the medicinal effect as well as the biological activities of sulfur-containing secondary metabolites and possible future avenues.

Television programs

description: In recent years, a rise in science and mathematics content has been observed in adult television programs. The programs CSI and Numb3rs, for example, frequently contain specific references to various science and mathematics problems. It is possible that a viewer's academic self-efficacy, defined as one's belief in the capabilities to organize and execute actions in the effort of goal attainment, may be influenced by such content; as such, television programs have the potential to positively engage adults in academics while simultaneously providing entertainment. To investigate this possibility, avid viewers of programs involving science and math were instructed to complete a questionnaire rating their chemistry and mathematics self-efficacy. In addition, the questionnaire examined viewers' understanding of specific science and mathematics topics before and after reading provided texts. Results showed a significant relationship between chemistry, but not mathematics self-efficacy and program preference. Gains in content knowledge were not observed in relation to program preference. Overall findings, however, indicate that adults may indeed engage with academic content in television programs. Such findings suggest that further research into academic self-efficacy and television content is warranted.

We show that, in the complex case, the Laplacians of the de Rham and Dolbeault complexes are discrete operators except possibly in degrees $n,n\pm 1$, where $n$ is the complex dimension of $V$. We also prove a Hodge theorem on the operator level and the $L^2$--Stokes theorem outside the degrees $n-1,n$. We show that the $L^2$-Stokes theorem may fail to hold in the case of real algebraic varieties, and also discuss the $L^2$-Stokes theorem on more general non-compact spaces.

Exploiting plant cell culture for natural product formation

description: The initiation of callus cultures and in vitro cultivation of plant cells, even in large bioreactors, has become a routine task. Despite the fact, that permanent cell and organ cultures can produce a whole range of small natural compounds (SNAPs) used in medicine, only a few could be produced at commercial scale. However, plant cell cultures provide very useful systems to study the biosynthetic pathways leading to SNAPs at the enzyme and gene level. They turned out to be ‘a pot of gold’ for those chasing the enzymes and genes involved in natural product formation. The use of genetically modified yeast and bacteria for the production of SNAPs is an emerging technique that will take research into the coming decades. This review contemplates and revisits developments in the field of using plant cell and tissue culture as tools to elucidate SNAP formation and means to produce bioactive plant natural products over the past 40 years alongside my own work.

description: We analyze work extraction from a qubit into a wave guide (WG) acting as a battery, where work is the coherent component of the energy radiated by the qubit. The process is stimulated by a wave packet whose mean photon number (the battery's charge) can be adjusted. We show that the extracted work is bounded by the qubit's ergotropy, and that the bound is saturated for a large enough battery's charge. If this charge is small, work can still be extracted. Its amount is controlled by the quantum coherence initially injected in the qubit's state, that appears as a key parameter when energetic resources are limited. This new and autonomous scenario for the study of quantum batteries can be implemented with state-of-the-art artificial qubits coupled to WGs.

description: Carrier induced ferromagnetism in diluted III-V semi-conductor is analyzed within a two step approach. First, within a single site CPA formalism, we calculate the element resolved averaged Green's function of the itinerant carrier. Then using a generalized RKKY formula we evaluate the Mn-Mn long-range exchange integrals and the Curie temperature as a function of the exchange parameter, magnetic impurity concentration and carrier density. The effect of the disorder (impurity scattering) appears to play a crucial role. The standard RKKY calculation (no scattering processes), strongly underestimate the Curie temperature and is inappropriate to describe magnetism in diluted magnetic semi-conductors. It is also shown that an antiferromagnetic exchange favors higher Curie temperature.

description: We prove that the error of the best nonlinear $L_p$-approximation by piecewise constants on convex partitions is $\mathcal{O}\big(N^{-\frac{2}{d+1}}\big)$, where $N$ the number of cells, for all functions in the Sobolev space $W^2_q(Ω)$ on a cube $Ω\subset\mathbb{R}^d$, $d\geqslant 2$, as soon as $\frac{2}{d+1} + \frac{1}{p} - \frac{1}{q}\geqslant 0$. The approximation order $\mathcal{O}\big(N^{-\frac{2}{d+1}}\big)$ is achieved on a polyhedral partition obtained by anisotropic refinement of an adaptive dyadic partition. Further estimates of the approximation order from the above and below are given for various Sobolev and Sobolev-Slobodeckij spaces $W^r_q(Ω)$ embedded in $L_p(Ω)$, some of which also improve the standard estimate $\mathcal{O}\big(N^{-\frac 1d}\big)$ known to be optimal on isotropic partitions.

BP Deepwater Horizon Explosion and Oil Spill (2010)
Resilience (Personality trait)

description: Natural disasters may bring devastating effects on the environment and humans. On April 20th, 2010, the Deepwater Horizon oil rig exploded, killing 11 people and spilling more than 4 million barrels of crude oil into the Gulf of Mexico.  The spill caused extensive damage to marine and wildlife habitats, the fishing and tourism industries, and the Louisiana, Mississippi, Alabama, and Florida coastlines.  Although people who lived in the area were deeply affected by the oil spill, most funded research have focused on the environmental issues, such as the effects of the spill on the marine ecology.  However, within weeks after the explosion, the National Center for Disaster Preparedness initiated the Gulf Coast Population Impact Project (GCPI) to track the effects of the spill on the people who lived in the affected area.  This thesis is a part of that project. The data for the thesis take a survey format in which respondents were asked about the health effects from the spill.  A limitation is that these self-reported diagnoses were not confirmed by medical professionals.  However, the dataset includes some information that medical records cannot provide, including data about the respondents’ location and sense of community. In this paper, potential association between people’s sense of community and their effects on perceived recovery at the individual, household, and community levels are investigated. This research is significant because it may help to identify factors that promote resiliency through community building towards natural disasters in the future.

description: We consider the stochastic higher spin six vertex (SHS6V) model introduced in [Corwin-Petrov, 2016] with general integer spin parameters $I, J$. Starting from near stationary initial condition, we prove that the SHS6V model converges to the KPZ equation under weakly asymmetric scaling. This generalizes the result of [Corwin-Ghosal-Shen-Tsai, 2018] from $I = J =1$ to general $I, J$.

description: Individuals who experience homelessness are exposed to stressors that have the potential to precipitate mental and physical health complications that can present serious threats to multiple areas of these individuals' lives. Although the path to becoming and remaining homeless is different for every individual, there may be some commonality specific to homelessness that makes certain individuals who experience homelessness more vulnerable than other individuals to the expression and potentially devastating course of psychopathology. Guided by the diathesis-stress model, the intent of this study is to explore the question, following a first hospitalization for mental illness ("schizophrenia spectrum disorder" or "other diagnosis"), what are the associations of homelessness with psychiatric symptom severity and how do risk factors of family history of mental illness, low intelligence, housing independence, hopelessness, and lack of social support interact with homelessness? To answer this question, a secondary analysis was performed on data from the Suffolk County Mental Health Project, a longitudinal study that sought to investigate the course of schizophrenia in an epidemiologic sample of first-admission patients. A sub-sample of 548 cases taken from the parent study were further subdivided into two cohorts; individuals diagnosed with schizophrenia spectrum disorder and those diagnosed with non-schizophrenia mental illness. A multilevel analysis was conducted for four different outcome variables, measuring psychotic, disorganized, and depressive symptoms as well as global functioning, in order to determine whether or not there is a significant association between homelessness and the severity of psychiatric symptomatology. Through the continued use of multilevel analytic models and interaction plots, significant confounding variables were examined to determine whether or not they facilitated interactions with homelessness. Homelessness was found to produce a small, but significant effect, for both cohorts across all four outcome variables. Additionally, applied to different outcome variables, the five confounding variables were also found to have small-to-medium-sized, significant interactions with homelessness. The results of this study provide additional statistical support to other studies looking at similar populations.

Brand choice--Mathematical models
Consumers' preferences--Mathematical models

description: Discrete choice models and the assortment optimization problem are the fundamental aspects of the broader field of revenue management, which now spans a broad array of industries such as airlines, hotels and online advertising. The main focus here is to first study the consumer preferences and their substitution behavior when they are faced with multiple options, explain those observed behaviors with mathematical models and then identify an optimal set of options to offer to maximize revenues. This dissertation enriches the choice models and assortment optimization fields by studying the setting when such options are available in multitude, either to the sellers or to the consumers to choose from. The first half of this dissertation focuses on the situation when sellers have access to a vast array of features to be chosen for products they want to offer. The second half of the dissertation focuses on the situation when customers are faced with a lot of options to choose from. This dissertation formulates concrete mathematical discrete choice models to tackle those situations, then studies the assortment optimization problem of maximizing the expected revenue resulting from these newly introduced choice models, and finally also designs efficient algorithms to solve them. Chapter 1 explores discrete choice models which capture consumer behavior and choices when faced with a set of different alternatives, and the resulting assortment optimization problem along with the different existing algorithms for solving them as well as the existing challenges therein. Chapter 2 models and solves the problem when the sellers have access to a vast array of inventory of products. Chapter 3 models dynamic preferences of consumers and the choice overload phenomenon when the customers are faced with a lot of options, and solves the ensuing optimization problem. Chapter 4 showcases the applicability and effectiveness of such models and approaches on high dimensional data from a field experiment on Flipkart, the largest e-commerce firm in India.

Associations of 'Eyes on the Street' with the Perception of Safety in New York City

description: New York City has seen major improvements in safety in the past few decades through enhanced policing strategies and camera coverage. However, public spaces and streets remain vulnerable. Recognizing the insufficiency of these strategies in reducing crime rate, this research sought to identify relationships between elements in the built environment with the ‘perception of safety’. Prior studies have proved that environments that ‘feel’ safer to pedestrians would increase their well-being and street usage which would consequently weaken the likelihood of crime. The elements in the built environment chosen for this study were inspired by Jane Jacobs’ “eyes on the street” theory stating that surveillance-generating elements on streets would reduce crime. To answer the question of how ‘eyes on the street’ conditions may affect the perception of safety on streets in New York City, a street survey was conducted in two selected sites. The results revealed that more people on streets, more street activity and more mixed-use zoning increased the feeling of safety while elements of disorder (i.e. trash on sidewalks) reduced the feeling of street safety. These findings inspired a set of recommendations on ways to improve street design and planning for creating environments that appear to be safer for pedestrians. A key synthesis is that achieving ‘eyes on the street’ by altering specific urban elements could significantly impact the perception of safety that may lead to actual safety.
