The Relationship

Existing literature on the relationship between ride-hailing (RH) and transit services is limited to empirical studies that lack real-time spatial contexts. To fill this gap, we took a novel real-time geospatial analysis approach. With source data on ride-hailing trips in Chicago, Illinois, we computed real-time transit-equivalent trips for all 7,949,902 ride-hailing trips in June 2019; the sheer size of our sample is incomparable to the samples studied in existing literature. An existing Multinomial Nested Logit Model was used to determine the probability of a ride-hailer selecting a transit alternative to serve the specific O-D pair, P(Transit|CTA)[1]. We find that 31% of ride-hailing trips are replaceable, whereas 61% of trips are not replaceable. The remaining 8% lie within a buffer zone. We measured the robustness of this probability using a parametric sensitivity analysis and performed a two-tailed t-test. Our results indicate that of the four sensitivity parameters, the probability was most sensitive to the total travel time of a transit trip. The main contribution of our research is our thorough approach and fine-tuned series of real-time spatiotemporal analyses that investigate the replaceability of ride-hailing trips for public transit. The results and discussion intend to provide perspective derived from real trips and we anticipate that this paper will demonstrate the research benefits associated with the recording and release of ride-hailing data. [1] This value defines the replaceability of the trip, where a value ranging from 0 to 0.45 is considered not-replaceable (NR), and a value ranging from 0.55 to 1.0 is considered replaceable (R).

The Objective of this study is to examine the effect of exchange rate system on the balance of payments, with a case study of a group of Arab countries. First we shed light on the most important theoretical and empirical studies of exchange rate systems and their macroeconomics effects in one hand. In the other hand we study a case of six oil exporting Arab countries. To achieve this purpose we adopted a panel data and run an econometric model to examine the relationships between the variables during the period 2000 to 2016. The study concluded that there is a significant positive correlation between the exchange rate as an independent variable and the balance of payments as a dependent variable, and there is no deference in the effects of the exchange system in the study of six Arab economies.

This study aims to develop a comprehensive integrated model which helps in explaining the impact of value chain integration’s (VCI)’s and relational capability impact on co-innovation in a network and competitive advantage. It also explores the role of value network-based co-innovation as a mediator in the relationship between supply chain integration and competitive advantage, and in the relationship between relational capabilities and competitive advantage of a housing bank sector. The study suggests that firm gains competitive advantage by utilizing value chain integration and relational capability. It is argued here that co-innovation based on value network has mediating role to create competitive advantage. The paper provides a discussion and implication on where value lies and how value is co-created in network of interdependent relationship and illustrate this by sketching a value map in network relationship and possible innovations that can be co-created in housing bank ecosystem. The study involved a single government owned bank located in different cities, therefore the results should be generalized cautiously. This paper constitutes an attempt to stimulate efforts and provide directions on the further conceptual development of value network-based co-innovation (VNBC). The newly developed measure of VNBC and CA exempt from past conceptual streams of the determinant of CA, could be used for valid measurements in future empirical studies in the field of strategic management. The paper provides a practical implications for managers to identify value and utilize new way of analyzing value-chain to create co-innovation within housing bank ecosystem. It also allows manager to practicing relational capability which gives the most impact to competitive advantage..

Abstract. This article examines transnational framings of domestic carceral landscapes to better understand the relationship between offshore and onshore enforcement and detention regimes. US detention on mainland territory and interception and detention in the Caribbean serves as a case study. While the US domestic carceral regime is a subject of intense political debate, research, and activism, it is not often analyzed in relation to the development and expansion of an offshore "buffer zone" to intercept and detain migrants and asylum seekers. Yet the US federal government has also used offshore interception and detention as a way of controlling migration and mobility to its shores. This article traces a Cold War history of offshore US interception and detention of migrants from and in the Caribbean. We discuss how racialized crises related to Cuban and Haitian migrations by sea led to the expansion of an intertwined offshore and onshore carceral regime. Tracing these carceral geographies offers a more transnational understanding of contemporary domestic landscapes of detention of foreign nationals in the United States. It advances the argument that the conditions of remoteness ascribed frequently to US detention sites must be understood in more transnational perspective.

Asymmetric Relationships

Purpose – The aim of this paper is to understand the process of value creation in business-to-business (B2B) contexts from the perspective of small- and medium-sized firms (SMEs). Small businesses are challenged to compete and collaborate with larger firms. While the “sharks” dilemma (often the most dangerous sharks also have the most valuable resources) focuses on specific defences, the authors emphasize a value generation perspective. Design/methodology/approach – The concept of asymmetric relationships is taken as a reference and examined using a longitudinal multi-case study. Findings – The authors results demonstrate how small firms not always assume an inferior, defensive position. Ambitious and growth-oriented SMEs learn to collaborate with larger partners and exhibit a proactive attitude towards relationship management. They understand the importance of developing social ties. They foster frequent and informal communication with their customers, favouring personal visits as a means to receive advice for directing their research efforts and exchange information and views. Such ties help them to develop shared plans and goals. Research limitations/implications – In asymmetric relationships, partner selection models should help firms to concentrate their efforts in a reduced group of key partners. These models should include not only economic performance indicators – variables such as flexibility and autonomy – but also innovation and improvement in processes, image, prestige and positioning, access to markets and stability. Originality/value – The authors found insight into a novel concept: dual-value appropriation, where partners do not split the pie of the total value generated, as frequently proposed in the literature, but fully appropriate a different and unique value from the relationship. The authors further highlight the important role played by the committed champions in developing communication and trust.

ABSTRAK Kelangsungan hidup organisme dipengaruhi oleh keseimbangan antara kandungan ion cairan tubuh dengan kandungan ion lingkungannya. Apabila gradient osmotik antara cairan tubuh dengan media lingkungan terlalu tinggi maka menyebabkan proses fisiologis terganggu, stress bahkan mengalami kematian (mortality) massal. Tujuan Penelitian ini yaitu mengetahui tingkat kelayakan kualitas air untuk budidaya udang vaname, menganalisis hubungan osmolaritas dan Tingkat Kerja Osmotik (TKO) pada udang vaname, dan mengetahui faktor kondisi udang vaname dalam kaitannya dengan TKO dan osmolaritas media. Penelitian ini dilaksanakan pada bulan November-Desember 2018. Metode penelitian yang digunakan adalah metode studi kasus dan metode deskriptif dengan metode pengukuran osmolaritas menggunakan alat Automatic Microosmotic Roebling. Sampel udang yang digunakan sebanyak 30 ekor udang vaname yang berasal dari 3 tambak yang ada di desa Mojo Ulujami Pemalang. Hasil penelitian ini menunjukkan osmolaritas media sangat berpengaruh terhadap tingkat kerja osmotik pada udang vaname di tambak intensif desa Mojo. Pertumbuhan udang vaname pada tambak intensif desa Mojo bersifat allometrik positif  dengan pola osmoregulasi hipoosmotik dengan nilai b=3.0618 dan nilai  faktor kondisi (Kn) = 1,621637. Hasil penelitian didapatkan nilai osmolaritas media pada tambak intensif udang vaname di Mojo pada salinitas 200/00 berkisar 616-618 (mOsm/l H2O) dan rata-rata TKO sebesar 37,36 (mOsm/l H2O). Tingkat kelayakan perairan pada tambak intensif udang vaname desa Mojo dikategorikan cukup mendukung tetapi perlu adanya perlakuan lebih lanjut. ABSTRACT The survival of an organism is affected by a balance between the content of ionic body fluids and the ion content of the environment. If the osmotic gradient between body fluids and environmental media is too high, the physiological process will be disrupted, stress will even experience mass mortality. The purpose of this study was to determine the level of feasibility of water quality for vaname shrimp farming, analyze the relationship of osmolarity and Osmotic Working Level (TKO) in vaname shrimp, and determine the factors of vaname shrimp conditions in relation to TKO and media osmolarity. This research was conducted in November-December 2018. The research method used was a case study method and descriptive method with a method of measuring osmolarity using an Automatic Microosmotic Roebling tool. Shrimp samples were used as many as 30 vaname shrimp from 3 ponds in Pemalang Mojo Ulujami village. The results of this study indicate that the osmolarity of the media greatly influences the level of osmotic work in vaname shrimp in Mojo intensive ponds. The growth of vaname shrimp in intensive ponds in Mojo village is allometric positive with a hypoosmotic osmoregulation pattern with a value of b = 3.0618 and a ponderal index (Kn) = 1 , 621637. The results showed that the media osmolarity values in the vaname shrimp intensive ponds in the Mojo at 200/00 salinity ranged from 616-618 (mOsm /l H2O) and the average TKO was 37.36 (mOsm / H2O). The level of feasibility of waters in intensive ponds of vaname shrimp in Mojo village is categorized as sufficiently supportive but needs further treatment.

Abstract In our paper, we redefine the category of “family” denoting the relationship of selected members of a post-noble/post-aristocratic milieu in Poland using Alain Badiou’s terminology. Badiou’s ontology based on a mathematical set theory and a generic theory is the most developed, complex, and revolutionary ontology of the 20th and 21st centuries. However, it is rarely adapted to new empirical studies probably because of its novelty and complexity. We do not intend to use the empirical case study made by Smoczynski–Zarycki to inform our argument but instead perform a translation of the Durkheim–Lacanian theoretical standpoint from “Totem…” into the category of “singularity” [singularité] in its relation to “the state of situation” [état de la situation] from “Being and Event” (Badiou 2005). This approach seeks to find a universalizing potential of nobility that will allow it to become a relevant subject for truth procedure analysis.

The current interest in organizational culture, identity, image and reputation and in organizational discourse points towards the pressure on contemporary organizations to focus attention on the symbolic dimensions of their activities. The phenomenon of branding, while originally portrayed as a marketing tool, can also be understood as an exercise in management of meaning. Branding does not only inform external stakeholders, such as customers and investors, about the values of the organization. It also potentially instructs and directs organizational members. In this sense, branding can be viewed as a management and leadership practice. Drawing on a longitudinal case study, this paper illustrates how these practices are played out in the particular context of a management consulting firm and explores the relationship between branding and organizational identity and identification. The study highlights the shortcomings of the strategic marketing perspective on brands and the need for further empirical studies that examine the role of branding from different perspectives and in different empirical contexts.

AbstractLegal scholars and philosophers have long debated the moral standing of the act-omission distinction, with some favoring the view that actions ought to be considered as morally different from omissions, while others disagree. Several empirical studies suggest that people judge actions that cause harm as worse than omissions that cause the same harm with the implication that our folk psychology commonly perceives this distinction as morally significant. Here we explore the robustness of people's moral intuitions, and in particular, whether the omission bias can be eliminated in the face of explicit and familiar laws that take away the moral standing of the distinction between actions and omissions. We show that although Dutch law allows both active and passive euthanasia, and although our Dutch participants were well aware of this law and supported it, they nonetheless showed a robust omission bias across a wide range of moral dilemmas. We conclude by discussing the relationship between our folk moral intuitions and explicit moral rules that are handed down by law and religion.
