Siblings as Confidants: Emotional Understanding, Relationship Warmth, and Sibling Self-Disclosure

Associations among (a) self-disclosures between early adolescent siblings, (b) emotional understanding, and (c) relationship warmth were investigated. Grade 5–6 children (M age = 11.5 years) were interviewed concerning the incidence of disclosures to closest-in-age siblings (20 = older, 20 = younger), feelings regarding disclosing (or not), and sibling relationship quality. Warmth was measured with the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985) and emotional understanding was assessed with the Hypothetical Relationships Picture Task (adapted from Schneider, 1989, & Aquan-Assee, 1992). Hierarchical multiple regressions indicated self-disclosure was positively associated with feeling good about sharing and negatively associated with reports of not trusting or not receiving emotional support from their sibling. Sibling relationship warmth was a key characteristic associated with both emotional understanding and self-disclosure; female target children demonstrated greater emotional understanding. Warmth, but not emotional understanding, was associated with self-disclosure. Findings are discussed in light of the importance of links between affective relationships and children's social-emotional understanding.     

An E-mail assessment of undergraduates' attitudes toward smoking.

Responses from 513 of 1,000 randomly selected undergraduate students who were sent an e-mail questionnaire, about cigarette smoking were analyzed. Thirteen percent of the respondents identified themselves as smokers. No statistically significant differences were observed between smokers and nonsmokers and year in college, sex, age, race, or having attended public or private high schools. Ninety-eight percent of the respondents considered themselves knowledgeable about adverse health consequences of smoking, yet 39.1% of current smokers seriously considered stopping smoking, and 11.5% of current nonsmokers intended to start smoking. The preferred quitting method of smokers and ex-smokers was stopping all at once ("cold turkey"). Fifty-two percent of the smokers did not want professional assistance to stop smoking; 40% of the nonsmokers wanted information on second-hand smoke.     

Ambiguity in asset pricing and portfolio choice: a review of the literature

We survey the literature that has explored the implications of decision-making under ambiguity for financial market outcomes, such as portfolio choice and equilibrium asset prices. This ambiguity literature has led to a number of significant advances in our ability to rationalize empirical features of asset returns and portfolio decisions, such as the failure of the two-fund separation theorem in portfolio decisions, the modest exposure to risky securities observed for a majority of investors, the home equity preference in international portfolio diversification, the excess volatility of asset returns, the equity premium and the risk-free rate puzzles, and the occurrence of trading break-downs.     

LGBTQI+ icons between resistance and normalization: looking for mediatization of emotions in hashtags

ABSTRACT

The mediatization of emotions emerges as an affordance of social media, the study of which involves paying attention to digital practices and to the construction and expression of public affection. This happens both for the great events and for the daily demonstrations of support or its denial. In this article we work on the phenomenon of the mediatization of emotions linked to two LGBTQI+ icons and expressed in hashtags on Twitter. Placing it in a specific context – the one of well-known television characters who have declared their homosexual orientation or transgender identity. The objective is to understand if the cloud of feelings they have created on Twitter is to be attributed to a true globally mediatized emotional exchange, or just an expression of emotions on the social media, and discover which emotional dynamics, linked to the LGBTQI+ world, they express.     

The Intermodal Bike: multi-modal integration of cycling mobility through product and process innovations in bicycle design

The paper presents the early results of the UE-FP7 project "The Intermodal Bike". The research aim is to provide a super-compactable, super-lightweight folding bicycle as a realistic solution to graft the cycling mode onto the root of the public or private transportation systems. The folding bikes now on the international market reach weighs between 12-15 kg, with a variable footprint but occupying -when compacted- an average volume of about 100 liters. To encourage the use of this vehicle and to extend it to a larger number of users with different characteristics, the research project has set its goal in increasing as possible compactness and light weight, creating a bicycle with a volume when compacted of 20 liters (reduction factor =5), with a shape of 48 × 36 × 12 cm and a weight of 5 kg. max., ensuring stability and improving vehicle usability and efficiency, during the ride and in the phase of bike folding. To achieve this goal ergonomic and usability tests have been carried out. The tests allowed to find a posture that would ensure efficiency and comfort in the ride to as many users as possible. Parallel tests were made on the vehicle usability in the urban transport system and intermodal. The need for light weight has required special studies on the optimization of the vehicle's architecture and research on super-lightweight materials.     

Experimenting new design languages in contemporary home design

The changes in society at the beginning of this millennium are giving rise to deep transformations in the behavioural trends and tastes of home users, as well as in their lifestyles and consumption patterns. This opens up a wide range of opportunities for innovation within the context of contemporary home design. Due to the emergence of new user profiles, new needs and models are coming to the attention of designers and manufacturing companies. Just think about the new needs resulting from the changing composition of households, new forms of cohabitation and the contemporary multi-ethnic society.     

Strategic approaches to sustainability in fashion supply chain management

Today, the sustainability challenge has become a relevant issue in the fashion industry. However, given that the request for sustainability is relatively new in this industry, empirical research that could guide companies towards supply chain sustainability is lacking. This study aims to deepen the understanding of the main strategic approaches to sustainability used in fashion supply chain management (SCM). Ten case studies were examined in terms of the practices that characterise these approaches. Moreover, contextual factors, drivers and barriers that support or hinder different approaches were identified. To accomplish this goal, both environmental sustainability and social sustainability were investigated, and all the areas of fashion SCM (i.e. new product development, source, make, deliver, retail, return, governance) were considered simultaneously to offer a wide overview of this industry’s sustainability issue.     

Skew Dyck paths

In this paper we study the class S$\mathbb{S}$ of skew Dyck paths, i.e. of those lattice paths that are in the first quadrant, begin at the origin, end on the x-axis, consist of up steps  U=(1,1)$U=(1,1)$, down steps  D=(1,-1)$D=(1,-1)$, and left steps  L=(−1,-1)$L=(-1,-1)$, and such that up steps never overlap with left steps. In particular, we show that these paths are equinumerous with several other combinatorial objects, we describe some involutions on this class, and finally we consider several statistics on S$\mathbb{S}$.     

An Attacker–defender Resource Allocation Game with Substitution and Complementary Effects

The United States is funding homeland security programs with a large budget (e.g., 74.4 billion for FY 2019). A number of game-theoretic defender–attacker models have been developed to study the optimal defense resource allocation strategies for the government (defender) against the strategic adversary (attacker). However, to the best of our knowledge, the substitution or complementary effects between different types of defensive resources (e.g., human resource, land resource, and capital resource) have not been taken into consideration even though they exist in practice. The article fills this gap by studying a sequential game-theoretical resource allocation model and then exploring how the joint effectiveness of multiple security investments influences the defensive budget allocation among multiple potential targets. Three false belief models have been developed in which only the defender, only the attacker, and both the defender and attacker hold false beliefs about the joint effectiveness of resources. Regression analysis shows that there are significant substitution effects between human and capital resources. The results show that the defender will suffer a higher loss if he fails to consider the substitution or complementary effects. Interestingly, if the attacker holds a false belief while the defender does not, the defender will suffer an even higher loss, especially when the resources are substitutes. However, if both the attacker and defender hold false beliefs, there will be lower loss when resources are complementary. The results also show that the defender should allocate the highly effective resource when the resources substitute each other. This article provides some new insights to the homeland security resource allocation.     

‘Being young and LGBT,what could be worse?’ Analysis of youth LGBT activism in Indonesia: challenges and ways forward

Young Indonesian LGBT people are currently mobilising against a wave of conservatism and violence in an increasingly anti-LGBT context. Young LGBT people are showing remarkable courage and strategic thinking and mobilising in a range of ways. These include grassroot peer support, advocacy, and partnerships with government, adult-led non-government organisations and the private sector. However, these youth also face multiple challenges. This article highlights findings from a 2016 study of mobilisation by youth LGBT activists, using in-depth feminist qualitative research methods. The aim of the research was to highlight the resilience of young LGBT people in Indonesia, the barriers they face, and to consider what feminists and development policymakers and practitioners can do to support them.
